I hate all this 18yr olds are kids stuff... if you are intelligent enough to go to uni you are intelligent enough to know that talking like this is wrong.

Nobody is suggesting that you are fully rounded at 18 and you won't make mistakes, be irrational or even sensible, but this is really base. . I would be devastated as a parent if my son thought in this way I wouldn't suggest that his age prompted those comments.
They are driven less by libedo and more by privilege, it was totally right for the university to expect better from their students.
