What do you think of these players?

Many times I have seen players who only play on one side hate the other, speaking very badly about him and his players. I don't share this at all, a while ago I came across a player who only played as a killer, who didn't understand that you can't judge someone just because they play, in this case, as a survivor. In the end I gave up because I didn't understand it and continued with my life, but it's something that impresses me how someone can mix a game with reality.
