Yeah, it was totally their fault. What a bunch of assholes.
I wasn't describing loners or anything like that. They had plenty of social experience. It was just a different culture and the culture wasn't particularly attractive to "outsiders".
As for "denying" them anything, I'm not sure what.
The main point I was trying to get across was that there are all sorts of people in the field. Not everyone is the same, even if your experiences lead you to believe otherwise.
Being social means being interested in others with different backgrounds from your own, and meeting them halfway. People who work in very technical field are notorious for neglecting to do this, and as a consequence they aren't particularly interesting to people outside those fields.
So yes, this is pretty much their fault, but it's not a death sentence, and it doesn't make them assholes. It just means they need to broaden their horizons a bit to make themselves more accessible and interesting to others.
