funny, i've been a hindu my whole life, and i'm most certainly not a vegan. Hindus are lacto-vegetarians by nature. No eggs, but dairy and vegetables.
Veganism, otoh, is a creation of wierd white hippies. I couldnt possibly live like that, with only vegetables, prepared in boring american styles. Hindu food is much more flavorful, and leads to less dependancy on meat. Lots of vegans go back to normal because vegan food sucks. But you'll be hard pressed to find someone who has been vegetarian from birth switching over. If you don't know it, you dont miss it, nor do you desire it.
I'm actually offended that you would limit hinduism so thoroughly. Milk is like key in most rituals, and almost all the desserts and sweets are dairy based. The vedas state that Between Meat and No Meat, you should go no meat. This only applies to the highest caste brahmins though. The warrior class was advised to eat meat to help aggresiveness and protection. The only absolutly forbidden meat is cattle. Lots of low caste indians eat chicken and fish, and some also eat mutton.
Oh, and i'm also not one of those vegetarian missionaries. I dont care what you eat, as long as there is something for me to eat as well. Nothing pisses me off more than self rightious punks who feel the urge to deride people because of their diets. I'm not going to take your meat away, and i'm not going to give up my dairy, so stop bugging me about it =)
Oh, and my white girlfriend became a vegetarian after we started dating, and i still can't figure out why =) I'm not complaining, but it still confuses me from time to time. But thats the hindu in me talking. Changing from your natural state of living to convert to a new diet or religion is just a foreign concept.
To come back to topic, there are many levels of 'vegetarian', and there was an interesting article in time magazine about it. If you do choose to go vegetarian, please make sure that you don't leave out the essential vitamins, and remember that it doesnt have to be tasteless to be healthy =)
As for me, 22 years without meat means that i cant eat it if i wanted to, as evinced by the sausage that was accidentally on my veggie pizza.... >_<
