1) Taste. I'd starve on any sort of non-meat diet. I'm very picky.
Being picky sucks. Mushrooms rock, despite what you say.
Not being picky myself, I can't say this with certainty, but I think pickiness stems a lot from upbringing. If people are brought up vegan, they're likely going to be more ok with vegan foods. That sort of related to my next point...
2) Convenience. Having to make special precautions when buying food or dining out would drive me nuts.
4) Fun. Enjoying good food with people is a lot of fun. I don't mean to say this is impossible to do with non-meat foods, but it definitely ruins a lot of opportunities that would otherwise be there.
...that pretty much all your points are things that stem from the world we live in, not from veganess or omnivority being a good thing/bad thing. The more people who accept it, the more that's going to change (and it HAS changed since 10-20 years ago). I realize that convenience is a fine argument for a single person to be/not be vegan, but I'd rather stick to the moral/ethical side of it instead of focusing on the artificial difficulties.
For what it's worth, once you get used to it, it isn't that difficult. It's far easier than I actually thought it'd be. It also depends how strict you are -- I know some people who will grill waiters about what ingredients they use, and who request having their food fried in a separate fryer than others'. Personally, I don't sweat cross contamination (to a point), and I try not to give restaurants a hard time. If it's reasonable to assume it's vegan, and they're busy or whatever, I'll just make the assumption. Yes, I've been burned on that before ("shit, that has mayo on it? Can I get another one?"), but overall it makes life easier.
3) Health. It's more effort to maintain a non-meat diet.
I actually find it easier. Far easier. After I became vegan, I became much more conscious of what I was eating, and my diet improved significantly. Part of the reason is that most fast food is off limits, so that instantly makes your diet significantly healthier. Another part is, previously I used to eat a lot of stuff that was basically devoid of any kind of nutrients (most meat is, and the vegetables were always tangential to the meal, when they existed); now, I do have meals on occasion (like my dinner today -- mushroom burgers and Tasti Taters (dunno if those are Canadian but whatever)) that have very little in the way of nutrients, but they're typically the exception instead of the rule.
Also, I'm assuming (feel free to correct me) that you're dismissing vegan food as something that you'd starve on without actually trying it, or even giving it a chance. I'd highly suggest finding some pure-vegan restaurants (there are usually some in every town, might have to use Google to find them) and trying out their food. It might be better than you'd think (it's absolutely better than I originally would have thought). Even my omnivorous friends (and all my friends are omnivorous), who often join me at vegan restaurants here (we're fortunate enough to have several in a smaller city) love the food. Maybe not even to be vegan themselves, but enough to understand what it's all about. It isn't all tofu and mushrooms
As for your disadvantages, I don't consider any of them significant. I'm sure there are studies that suggest these things, and I'm sure they have some merit, but there are a few caveats that I suspect you're ignoring:
1) The magnitude of the increase in risk is probably trivial.
2) People who have non-meat diets tend to be more healthy people overall (exercise, diet, etc.), which decreases their risk anyway, and it makes the numbers meaningless. Unless the studies you're implicitly referencing here account for this, I'd be very skeptical about your conclusion. It'd have to compare vegans with slaughterers who have comparable physical activity levels, healthy eating habits, etc.
3) I'm sure there's a higher risk of eating contaminated food, and that's a reasonable consideration. However, I'd send you back to (1). The increase in risk is probably trivial. In the 22 years of my meat rich diet (YUMMMM), I've never had symptoms of having eaten 'contaminated food' that were noticeable.
<edit> For benefits, I don't buy "it tastes good" as any kind of argument -- that's like saying "rape is ok because it feels good!". While that may be the case, it's only good for one party -- the other is suffering, and losing something important. Killing stuff for simple desires doesn't really count as a "benefit", in my books. I'm looking more at nutritional value (which is nearly nil for most meat).
Ignoring taste is stupid, and your response is completely silly for the following reasons:
1) I'm not concluding that eating meat is okay just because it tastes good. I don't deny that this contributes to my argument, but it isn't the only consideration. Your argument assumes it is.
2) If you're trying to conclude that rape is okay, "it feels good" certainly contributes to this argument. Alone, I would say it's a completely silly argument, but it's equally silly to ignore that it provides a non-negligible amount of support.
Blah blah blah... it goes on and on. I am impressed that you are able to maintain a vegan diet, but I am not at all impressed by your ability to argue that it is the only reasonable diet.
The best way I can really address any of those points is, pick a few vegan blogs and read them for a few weeks, without dismissing everything at the outset (in fact, research everything they say). Watch videos they link to, try recipes they post, see how terrible (sorry, editorializing
) factory farming is, and really try and consider their viewpoints, even briefly.
As a single source, and as somebody who's still fairly new to the lifestyle (it'll be 2 years on Halloween
), I'm not the best source. In addition, there are a lot of reasons to do a vegan diet, and I'm not giving credit to all of them (or giving them all the amount of time/discussion they deserve), I only talk about my own reasons.
And as for the rape bit -- I think you misunderstood my point. I didn't suggest that you said 'tasting good' is the only reason; rather, I said that 'tasting good' isn't a valid reason, so I wouldn't buy it, and I wanted other things.
Keep in mind, it's not like I woke up one day and decided that meat tasted bad -- I used to love it, and I'm sure I'd still like the taste. I've even thought that I could never be vegetarian for pretty much the same reasons you present (except the part about being picky, I'm not picky). For what it's worth, when I was your age, I definitely would have said the same thing you're saying, no doubt in my mind. As I grew up, I decided that the lifestyle I'd been living was wrong, and I've been able to change a lot of things.
Also keep in mind, you're only seeing one side of the debate, since, as you said, you've been on that side your entire life. Me, I was an omnivore for 24 years and a vegan now for two (I was never really a vegetarian -- I live by the 'go big or go home!' principal
). I think you have to try both sides before you can have a reasonable opinion.
