I don't care so much when people are vegetarian/vegan. In fact, a few vegetarian friends of my wife occasionally come over when I BBQ and they enjoy all of the non-meat BBQ. What I cannot stand are the preachy vegans/vegetarians who tell me how unhealthy I am supposedly eating. Usually I just nod and smile.
