Debate about being vegan/vegetarian here

Control yourself. And not wanting animals to be abused horrifically or killed in factory farms is kind of sound thinking. Sorry if I sound like a musty, crusty, rusty, dusty, stupid, “acoustic” pain in the bum that no one gives a dam about for that, but not actually.
They don't have to be mistreated to be turned into meat in the first place.

Vegans dont have animal product. Now if fossil fuels really are from fossils, which is controversial, that's an animal product, so they can't use fuel. They can't even use electric cars, because a lot of the energy for those come from coal.
