I view vegans and vegetarians much the same way I view Christians and Mac fans. I wouldn’t mind them at all if they weren’t so damned evangelical about it. I was vegetarian for about three years, but I tried very hard not to be a vegetarian evangelist.
Check out Fat Head on Hulu while it’s still available. It has a clear liberty perspective with an emphasis on personal choice and responsibility. It’s two hours, but it flies by because it’s really entertaining.
