Rebellion is only tolerated to the degree which it will not challenge established thought patterns and ways of life. Thus, not making it "rebellion" at all.
I'm vegan. A vegan is someone who does not eat meat and/or animal products. Prior to recently becoming vegan, I was vegetarian for 10 years. A vegetarian is someone who does not eat meat. And yes, "meat" includes fish. I have no idea where that delusion comes from. A pescetarian is someone who still eats fish. I used to prefer to use the term "hypocrite," but these days I don't think that's entirely fair.
Living in Vancouver for a long time, I found a very veggie-friendly community, covering the broad spectrum of vegan, vegetarian, pescetarian, and tourist. A "tourist" is someone who most of us know, or who at least in the context of speaking to a vegetarian, will say, "Yeah, I was vegetarian for 2 years, I couldn't keep it up" (as though every person alive will ultimately fail as they did). Tourists usually are doing it to follow the latest health fad they read about in Shape magazine, or feel that cutting meat out of their diet will help them to lose weight. Well, it will, but if you don't research your decision and learn more about your own biology as a human being, you will develop the stereotypical "vegan" look: rail thin, gaunt, and pasty, or "heroin chic" as it's been sometimes called.
I became vegetarian 10 years ago at a time when it wasn't as "popular" amongst celebrities and, henceforth, non-famous people. It was a struggle because at the time there wasn't quite the same range of vegetarian options in the supermarket (in those pre-Yves days), but because I was doing it for political, cultural, and social (though ultimately personal/ethical) reasons, I held my ground and through learning about daily vitamin and mineral requirements, protein, digit-by-digit alternatives, and just the general and basic requirements to maintaining a healthy body, I was able to successfully transition and have never looked back.
I am surprised and amused that still, after all these years, upon revealing that I am vegan, I am faced with genuinely concerned looks or morcels of fear and/or confusion (as though fear is somehow not entirely of that which we do not yet understand). Of course, the responses are always incidental to being in a dining situation. I'm not one to wear a "Meat is Murder" t-shirt; I keep my dietary choices to myself and don't claim that meat-eaters are morally bankrupt, nor do I need to be lumped in with so-called "activists" who blow up meat factories -- vegetarians like that give the rest of us (vegetarians and activists) a bad name. Vegetarianism is a proclamation of passivity and non-violence. Why would I firebomb your restaurant if I found out the sweet potato fries are cooked in animal fat? Though I must admit, instilling a healthy fear amongst restaurant waitstaff when I drop the "V"-bomb is rather amusing but at least it ensures vegan-friendly dishes and cooking methods. But naturally then comes the classic line: "So... what do you eat then? How do you survive?" Well, for one, I'm honouring a cultural history in India of vegetarianism, where my family has existed for centuries and centuries. Go to certain parts of India, order beef, and get mad or call them "hippies" when they tell you beef's not on the menu. Do it now, I dare you! The assumption that meat is "essential" to a human diet not only discounts an entire nation's history and is, frankly, severely ill-informed and borderline racist, it also dismisses the millions of years that humans lived prior to agriculture and mass production, during which time meat was not a primary source of protein or nutrients in a human diet. Furthermore, if a life had to be taken for consumption, very strict procedures were followed around ritualistic sacrifice, use of the animal, and acknowledging its place in the cycle of life, never seeing it as a means to an end or a pawn in a game of human domination of the planet. Genesis 1:28 isn't necessarily a directive to destroy and exploit all non-human life in the interests of human expansion -- in spite of what some archaic Biblical "scholars" may try to impose.
The thing that throws people for a loop is that they expect me to look like a starving Ethiopian baby because I am vegan and, surprise surprise, I don't. I have muscles, broad shoulders, and a strong cardiovascular system, and do not fit into the preconceived formulas of what people think a vegan looks like, and the over-dependence we have on animals and animal products in our day-to-day diet. I eat very well, have developed an even greater appreciation of diverse ethnic foods in light of not being able to rely on simple meat and potatoes. More so, pretty much everyone I know absolutely loves coming over for a home-cooked vegetarian meal, meat-eaters or not, usually saying, "Wow, if I ate like you guys (meaning my wife and I), I could totally be vegetarian." Thus we face the reluctance to become vegetarian on the ground of, "I like the taste of meat too much." My response, always: "Give me an hour and your favourite recipe and I'll make a vegetarian version that will satisfy you equally, if not more, especially in the long-term. It's not the actual meat itself that you like the taste of, it's the spices, the seasonings, and the treatments -- you can make anything taste the way you want it to if you cook it properly. And your B-12s, proteins, and irons can be easily supplemented without having to pop a million pills."
Whilst I normally try to explain the massive range of wonderful food options I have available to me as a vegan, I am often received with glazed eyes and judgment (and frankly, I get kind of bored of answering the same three questions over and over again -- and do you really care why I stopped eating meat when you live under a worldview that treats anyone who does not as a malcontent and only tolerates "rebellion" until it actually forces you to introspect and examine your own patterns of thought and way(s) of life?)... so, I'm pondering just stopping the sugar-coating, cutting to the chase, and saying: "A vegan is someone who does not eat meat or animal products. Humans, on the other hand, don't fit into that category because modern science, philosophy, and religion have taught us that we are in a class above animals. So, as a vegan, I get my protein from a freezer full of unsuspecting murdered Catholic school boys. But I'll call it 'soy' if that's more PC."
Though I suspect that would probably alienate people (and vegetarians/vegans are already marginalized enough socially). Keeping the open invitation to dialogue open is, as it always has been, the way to go. Such as asking the question to meat eaters: "What is it about my vegetarianism that offends you so much? Why does it mean so much to you to eat meat that you feel the need to ostracize me, or try and pick apart every so-called 'inconsistency' in my point of view or way of life?" Do I come up to you and say, "If you're not gonna eat human flesh, you may as well not bother eating meat at all"? No, I don't, because I'd be a jackass if I did and you'd never hold a conversation with me at a party. Yet, it's perfectly fine coming from the other side, and you wonder why I may walk away after a few minutes (and then it's me who's the asshole?). Frankly, eating meat is just as much of an ethical standpoint as not eating meat; it's just not seen as such because meat-eating is the "conventional" practice in this culture. Lest we begin a discussion of rebellion, counter-culture, necessity and deviance, and other concepts too grand to comprehend in a 140 character Tweet.
So come chat with me next time you see me. I promise I won't bite (like a good vegan). I may nibble though.
