>The flipside of this is the reactionary multitudes who spout 'sjw' or 'virtue signalling' or 'socialist' when someone on the left questions the status-quo.
A fair point, however, I think the only way to reverse the trend on the left is for the right to employ the left's own tactics back against them, in spades. The right needs to destroy the lives and careers of, for example, some university presidents who allow this sort of brutish behavior to go unpunished, sometimes even making excuses for it. Or go to war against companies who cave to the SJW demands. It has to be mutually-assured destruction, not one-sided.
