I'm not a vegan, so I'd be a pretty terrible liar if I was trying to guilt trip others into being something I'm not.

My point was that if you think in terms of meat, or horses, you'll only be able to come up with solutions to your problems in those terms.

If you go one level up and realize that your problem has nothing to do with horses or animals, and deals with transportation then you'll realize you can solve that problem and never have to deal with horses again.

People enjoying horse riding is in fact a completely unrelated problem (entertainment, enjoyment, or whatever you want to call it), as I was making the point by mentioning cannibalism (you're doing it because you enjoy it, not because human flesh is necessary for your sustenance).

If you open your mind to the fact that it may be that what you enjoy about your food isn't the meat but the flavors and effort the chef puts into the dish that just happens to contain meat, you'll see that you're probably associating that deliciousness with the meat when in fact it's just because the deliciousness was imbued onto the meat dish. We started using meat because of its convenience, not because it has some magical properties that make food palatable where other things cannot substitute.

I personally am not vegan because animal welfare is not high enough in my priorities to overcome the hassles of adjusting around the current bias towards meat in most cuisine. But if most cuisine started orienting around non-meat dishes (and a lot of cultures already do this, especially from countries that historically couldn't afford meat), I know I would not complain.

It's uniquely American (maybe European too?) to eat a giant slab of relatively cheap lean steak with just salt and pepper... most other cuisines mix meat with veggies, or in the case of Japan go for slightly higher quality (non-factory farmed) but lower volume meat consumption. Veggies in American cuisine are an afterthought (something you have to eat to "balance" your meal) whereas if you take Chinese dishes (while many feature meat), they can often center around veggies and make them the primary focus.
