Give him time. He is still trying to process Trump losing.
I think Trump losing has just pushed him over the edge, he's gone nuts. Like you say it'll take him some time to find another retarded cause to support, he'll be back to normal then

The motive is trolling, that's all. His comments read like a right-winger pretending to be left and then calling out anyone who says anything vaguely right wing/non-woke for his own amusement.
It's actually an anti-left thread masquerading as an anti-right one.
It's a load of toss is what it is, but then I think everyone knows this.
