I mean, setting a good example to everyone on the table without forcing myself on everyone is fine. I'm vegetarian and dont eat meat. My family respects that and makes me an alternative.
But I will definitely.I will not disrupt and ruin a nice and peaceful dinner by lecturing everyone at the table for 1 hour so i can feel good about myself.
