As a humanities student in the Netherlands, I see no sign of left SJW's ruling campusses. I can't comment on the US, sure, but my university explicity said that they would not censor or remove any unwanted lectures or topics. My faculty has regular lectures, debates and discussions on sensitive matters such as slavery, Nazis, Holocaust, Immigration and terrorism. Not once has anyone protested against this or got triggered. Never heard of that. Never heard of anything like that from friends studying elsewhere. So at least in my country, universities are far from ruled by leftist SJWs. If anything, the Right winged libertarians are doing very well here.
