The riots at UC Berkley and at the University of Missouri are facts, not right wing propaganda.They were driven by the Left, not the Right. It is also a fact the Leftists on campuses are preventing conservative voices from speaking.
In answer to your question, even one University is one to many.
Instead of attacking those of us who have a different viewpoint than you do,  why don't  you
actually do a little unbiased fact checking. If you do, then you might be as concerned about the crap that is being spewed on campuses as I, as a parent , am....or you could just pay $40,000 per year so your little darlings can get a worthless degree as a  Social Justice Warrior or in Anti White Privilege.
