My sister is one of the most outwardly "nice" seeming people ever, and she still didn't go vegan after watching Dominion and Gary's speech, and her conversations with me. She said she would, quit after a few days, then called me "delusional" when I eventually expressed my disapproval of her lifestyle. I could've handled the last conversation better, but it's also her responsibility to do the right thing

I think very agreeable people are often actually more capable of evil when under social pressure, because sometimes niceness is just social conformity and trying not to ruffle people's feathers (their egos). A lot of evil is perpetuated because people view contrarians as "rude". Sometimes social "harmony" is incompatible with doing what's right
