Do universities have a code of conduct for their students? And if not, should they have one, that all students sign up to, that includes what constitutes unacceptable behaviour in person and via text/phone/social media etc - with appropriate sanctions set out in the code?
I am the mother of three sons, and I would consider myself an utter failure as a parent, if any one of my sons went in for this sort of 'bantz'. I am as sure as I can be, that they would not do this - that dh and I have taught them to respect other people, and how and where to draw the line where banter is concerned.
Banter, in and of itself, is not wrong - as long as everyone concerned is laughing. The women at Warwick were not laughing.
