I have an irrational hatred of vegans
Why is is that you hate vegans?
I read that many vegans don't eat meat because of how cruel meat production is for animals.
Hating people for their choices isn't uncommon, but it can be hurtful. Some people become vegan for lifestyle reasons, but others make the choice because of allergies and health issues. Hating everyone for one view is being shortsighted.
I also think it's a waste to be vegan. They're making eating pasta and pizza a moral issue.
It doesn't seem like someone being vegan impacts you at all. Also, not eating meat because of animal cruelty seems like a great reason, and you shouldn't hate people because they make you feel guilty.
