i think turning vegan is a bit like when u find a new religion to believe in, you go a bit religious fanatical at first, then you start to calm down about. my whole family eat meat but i cant hate them for it, even if its not for 'health' reasons like your partner. i just try to show them other options because i think our society is still very meat obsessed and they dont understand what other choice they have to eat, they dont think about the process that meat has gone through and its the blind ignorance that pisses me off, alot of meat still gets wasted and that always upset me even when i was a meat eater.
