If someone wants to deny themselves pleasure in life (the best foods in the world always have animal products in them) that's their choice, but vegans almost always proselytize. They LOVE to tell you that you're destroying yourself and the world by eating an egg or having real cheese on your pizza. What they fail to realize is that being a vegan is absolutely a first world choice. Most people in this world are thankful when they have enough food to keep from starving. Only someone living in one of the countries that openly steals resources from others has the luxury to choose what to eat and what not to eat based on ethical concerns. Basically, most vegans in my experience are spoiled, whiny, self-righteous assholes. Hopefully that will change someday.
