I think you’re wrong on the learning Japanese front. There’s plenty that doesn’t translate to subs or subs well. I’m not spending the time to learn Japanese for that though. But I’m not gonna diss anyone who does.

Sorry you’ve had such bad experiences with the fandom. But I think that kind of stuff comes with most things with an actual fandom. Fan comes from fanatic after all. There’s seemingly always people to take things too far or too seriously. It’s entertainment. People need to lighten up.
