Why do vegans have this weird fascination with perceived cleanliness  when it comes from animal source foods? 
"You know you are eating pus?" 
"You are basically frying and eating menstruation?"
"It's filled with hormones!"
YOU ARE EATING A ANIMAL! It is messy, unclean, full of bodily fluids, shit piss cum pus blood as far as the eye can see, and we make it edible, THAT'S THE FUCKING POINT.
The idea of eating a animal is clean only exists in the minds of urbanites that only se meat neatly packed on the market freezer.
