I'm noticing quite the same with vegetarianism. I became vegetarian around 15 years ago, when it was still a marginalized group of people. Somehow also particularly as a man, my eating habits felt like a personal affront to other men, at least based on their reaction.

I generally don't tell people these days, if I can avoid it, despite having had multiple colleagues that were openly vegetarian/vegan. Like, at one point, I felt like the outsider, because I had three veggie colleagues discussing veggie food and I felt like I couldn't participate without blowing my cover, so to speak.
Fucking ridiculous, the amount of emotional abuse one goes through, for not wanting to eat meat or liking humans.
