I don't know about that. Your baseline for group behavior seems rather... off compared to my own (and most other people's, I think). A lot of sessions that you've described as "mostly okay" or something like that have stuff that would at best make me very vary of playing with these people, while the sessions you actually complain about would make me never play with them again, move across the country and change my identity. (Okay, I'm exaggerating a little, but not that much).
