You must take into consideration that not all educational systems are the same, and not all may try to further their knowledge as you might have. But you really should make sure you don't take your anger out on people you just met. You leave bad impressions that way.
Other than that, I'm willing to give you another chance. But I'm only lenient to an extent, so if problems like this occur often for you, you may want to rethink if you want to be in the group. Or be flexible with the crowd.
