Earlier this month, the world witnessed a group of hockey players from Stirling University chanting sexist songs about miscarriages on camera, while performing Nazi salutes. Other students watched in horror; too afraid to do anything to stop the perpetrators. This is what banter is. It is grossly misogynistic. It is racist. It is hurtful. It is ignorant. It is the vindication that justifies all of these things - all in the name of a harmless joke. And it needs to stop.
