Although I don't disagree no one should be typically outright shamed for having a different opinion as Burgo suggested. (which I feel hasn't happened here) I was just about to ask the same thing. what is the psychology behind it generally speaking? I don't want to have fun in game now because I'm going to have fun in the other game later? okay sure.. you're free to play it that way, its different, but ok.
I don't think we were being exceptionally rude more so than real.. I'm guessing you mean when Ephemiel said to leave? that strikes me as a passionate response of fandom to someones time investment anxieties or whatever imo. Also you can't censor the DDDDLife she makes some fair points maybe with a bit of attitude but would we really want it any other way?
..what would have been pathetic would be if ppl had said to leave because they think ill on you as an individual and because you can't read ancient roman backwards out loud and for reasons entirely unrelated to the game, not for your avaunt grade stances on things in light of the NG.
