Despite my earlier joke......
I have friends that due to health or religious reasons eat a pretty strict plant-based diet. One is a member here.
One of my most trusted minions is also a vegan. She's not crazy about proselytizing that, and accommodating her needs when we go for a team lunch of not a problem. She has a pet pig named Becky who is sweet, affectionate and very smart. She's probably pretty tasty as well, but I'll never know.
I make a point of not eating a blood-rare steak in front of my Hindi friends, and they refrain from picketing my back patio on the weekend.
Respect - it's a thing.
