But I find is that vegetarian propaganda is many times so disgusting and based on lies that it's probably going to turn people away from vegeterian food. Some vegeterians and vegans are obnoxious bigots and their efforts are generating opposite result - people start hating vegeterians and vegeterian food.
So I don't evangelize vegeterian. Besides, my reasons are too complex for most people to understand: "But chicken and cows were created for us to eat! They are not suffering!".
