THAT’s how you deal with lib histrionics. Like demons, they have no power over you unless you let them. No apology, no backtracking, no effort at communication with the party that had forsaken every avenue of communication.
It’s fascinating how far our real and putative representatives in the public forum have come. Once you understand that your political foes are irrational, fanatical, that they hate you, that they will destroy you the moment you show good-faith softness (witness SJWs’ destruction of anyone who apologizes for a minor ideological misstep) – you stop treating them like a legitimate party. Like a rebuffed demon, the liar-lib is reduced to impotent howling.
