Oreos are vegan friendly. It's amazing, but I suppose every group has to have at least one good "food." I have several friends who are committed vegans. From my experience, they spend a vast amount of money and time preparing vegan meals that they rave about. In the end, the meals taste sub-par at best and really nasty at worst. This isn't to say that there aren't good vegan foods, but they do tend to pale in comparison with more normal fare.
The health benefits of being vegan are questionable. Humans are built to eat meats. Yes, there are alternatives that for the most part take care of one's needs, but they are often lacking in some regard. OP, if you're looking for a trendy diet, look into being a Locavore. I have a great deal more respect for these people, and the diet makes sense logically.
Also, almost all vegans, as has been noted, are pretentious, stuck-up, and hang around other vegans almost exclusively. This way they can pat each other on the back constantly, and no one ever questions them. Vegans, almost entirely, are anti-hunting, anti-progress, and anti-EVERYTHING. They hate on a tremendous number of things, without offering any viable alternatives that work for society as a whole, rather than one secular group.
Even though I have good friends who are vegan, I still tend to look unfavorably upon someone who tells me they are vegan. Also, vegan girls are about the least attractive demographic out there. Seriously, veganism says nothing about no razors, dental work, etc. That doesn't even start with the Better-Than-Thou attitude that goes without saying.
