Not to be petty, but, while there is plenty of merit to the idea that there are persecutors on the left, my experience has unfailingly been that the right continues to hold (to the misfortune of all reasonable conservatives) an incomparably large share of the kind of hatred and desire for violence against one's own countrymen that is illustrated by the parent post. So it was in the 60's, and so it has been since. In fact, Trump's support for that attitude and that segment of his base is a big part of why the left reacts so strongly to him.
