I’m afraid this kind of thing  is getting to be more and more common.
The professor involved should be publicly shot, in my view.
As it is, the university issued a statement from Prof Wilkie apologising to Mr Duvshani and making clear that he was not speaking on behalf of Oxford.
The release reported that the idiot is ‘under investigation’ and went on to say “Freedom of expression is a fundamental tenet of university life but under no circumstances are we prepared to accept or condone conduct that appears to, or does, discriminate against anyone on grounds of ethnicity or nationality, either directly or indirectly.”
He’s supposedly under threat of dismissal. I’ll be watching this one.
