I don't watch Rogan religiously enough to know what his opinions are on every single topic under the sun. But I do watch him enough to have the opinion that despite claiming not to be a right-winger, he does hold a solid list of right-wing views and this is perfectly fine as long as it comes from a right place and I suspect it does -- I know a grifter when I see one and he just doesn't give me that specific vibe. That said, anything Covid-related (be it on vaccines, masks or restrictions) and he becomes a disingenuous idiot in an instant. So far he has refused to listen to actual experts, invited a doctor with fringe opinions to his podcast and the list goes on.
He never claimed to be an expert on anything other than martial arts, sure, but he's that big of a podcaster that it is plain irresponsible to spout utter bullshit about a deadly disease knowing his scope of influence.
