I wonder if this liberal word means that liberals think that Trump constantly lies, or whether they think that that there no longer is such a thing as truth. It no longer exists, so they can say whatever they like.
I think probably the latter. Most liberals wouldn’t understand what truth means if it hit them on the head.
The point is that factually correct means nothing in the face of politically correct. I believe it goes back to some of the gallows humor of the old USSR.
