Unless you have been living under a rock you will know college campuses are being taken over by far-left activists and filled with safe spaces and other anti-free speech laws. It may not be the case in a few smaller colleges (BTW, if you are teaching without a degree, I am guessing you aren't teaching at Harvard!), but it is happening at top universities like Yale and Berkley.
Obviously, you won't learn this stuff if you stick with Huffington post or CNN... or you are so far to the left yourself you don't recognize the problem when you see it.
