Hes now endorsed Desantis, a person aggressively at odds with Bernie Sanders on a every single political position.

Still think he supports Bernie?

I don't think anyone has said he never supports things that are true or positive. That might almost be better because it would make it clear that he's just a nut job like Alex Jones. The complaint is that he gives an equal platform and equal credibility to factual and unsupported ideas, so people end up giving equal credence to both.

It's like when news platforms felt they needed to give equal time to both sides of everything, so they gave as much coverage to climate change deniers as climate scientists, fueling the public scepticism, even though climate change deniers were a fractional percentage of the scientific community. Most agree now that that was a mistake and is partially responsible for the issues we're facing today.
