As Rogan says time and time again, he is a moron, therefore you shouldn't listen to him and most important of all you shouldn't criticize him for what he says. After all, he is a self-described moron that people shouldn't listen to.
Since Joe Rogan knows that no one will listen to what he says, which is of course why he calls himself a moron (it's not just a cowardly deflection to avoid criticism, I promise), it makes perfect sense to release political ads comparing anti-vaccine measures to the Holocaust. After all, no one puts out political content for political reasons.
By the way, Joe Rogan is a moron, so this is fine.
Oh, and Joe Rogan is a leftists that loves Bernie Sanders. The fact that he supported Trump and literally came when Texas turned red is just because he's a moron, not because he wanted Trump to win and because he believes Texas will die with a democrat in charge. He did say those things, but he's a moron so that's fine.
