Actually, he's not lying. I've seen Jack has throw around the word racist rather liberally at times, especially if it's someone he disagrees with. I can't remember the thread title, but there was one particular thread where Jack, while not directly saying it, implied that he wasn't white. It wasn't that long ago.
I know people love to get on their knees and brown their nose in the crack of Jack, but I've seen glaring holes in the armor of the intellectual giant role he poorly attempts to play. His largest fault, like many on the left, is his naivety when it comes to identity politics. He is only too willing to believe anyone who throws out the words racism, misogynists, rape culture and homophobic while failing to see their cruder intentions. He seems completely oblivious to the current role many leftists have taken in ruining Universities and Journalism.
