Indeed. I used to have a circle of friends/acquaintances that had a huge number of vegans and vegetarians. I can honestly say I have encountered literally 0 vegans or vegetarians ever mention it unless food was being served. But if food is being served,I mean…you really can’t avoid having to tell everyone.
On the other hand, I have witnessed a huge number of meat-eaters become insecurely defensive, aggressive, bullying, harrassing as soon as anybody mentions that they don’t eat meat.
