That is deplorable.
If colleges allow freedom of expression, pretty soon the entire university will need to be a safe space.
Freedom of expression should not be allowed if socialists, imbeciles and weaklings don't like it. Freedom of speech should be applied selectively and carefully, lest it bleed over the line and become micro aggression.
Non pc students should be expelled. Just the white ones.
