Well, over the past 10 years (or at least that's how long I've noticed it for), liberal politics have been adopting some of the more annoying traits of conservative politics from about 60, 70 years ago. Like, when some piece of media offends them in a way that doesn't even have anything to do with them, in that case it was certain books and music, they demanded it be shut down, and burned a lot of the copies in existence. The same thing is happening among the left, this time in the digital equivalent.
