As much as I don't like Trump there is an element of truth in his criticism of the "alt-left". These are people who shut down speakers at universities , cause riots at G20 meetings and try to impose their views with out listening to others. Much like the Alt right and ISIS. 

What ever happened to "I don't agree with you but I will defend your right to say it." I thought that was the basis of our democracy.

This political correctness   has reached the epitome of stupidity when it was announced that sport announcer Robert Lee was pulled from the Virginia football game because his name was the same as the confederate general.  
BTW Robert Lee is Asian.
