On the "grow a thicker skin" part there are quite of few people out that that do need to do this. Cause there is lot of people that get offended by almost anything, I agree that there are also lot of mean and rude players on the game which do take stuff too far but there plenty of people on both sides of the fences on that issue.

I don't really have social anxiety, I'm just very much a introvert and prefer to keep to myself but I have no problem getting online like in this game and talking with people. I actually talk more in game then I do in RL.
