The left has taken to rigging debates and disseminating falsehoods repeatedly after being corrected. They don't seem to care in the least who knows it. It should go without saying that they are going to select only content which advances their narrative.
I truly believe that they have been driven over the edge by the election of Donald Trump. They will bring the GOP down or go down in flames trying.
The sheer lack of fact, logic and decency in the general discourse (the right is not doing a lot better) makes me think we are a tinderbox waiting for a spark. Can't say that I am sorry to own a gun or two.
