I don’t think many people truly hate veganism, they are just frustrated by a few of the louder vegans out there.

For example, some vegans are very judgy - they will unabashedly tell non-vegans that eating meat is morally reprehensible. They also often want you to watch brutal videos of animal abuse and slaughter, with the overt overtone being an accusation of “you are doing this. It’s your fault if you eat meat.”

I’m not sure how any person who isn’t vegan could possibly see that as anything but unwelcome. Life is hard enough without this sort of thing.

This said, I know plenty of vegans that never do this. I think it’s awesome that they can avoid meat, and I applaud and support alternatives like impossible and beyond.
