But he wades into deeply political issues. I agree, he should steer clear of that, for the most part, but when he gets involved, people are going to critique him on those terms.
For example, when he hosts Dan Crenshaw and lets him spout GOP talking points unchallenged, people are going to criticise him for that. He's got an explicitly political, explicitly partisan guest. Why? Why do that if "Joe doesn't do politics"?
I think Joe is a relatively honest fellow who is open to hearing a spectrum of opinions. But I've seen RWers take advantage of his eagerness to find common ground. They roll in and pretend to be super reasonable, while misrepresenting their positions and the positions of "the left".
Occasionally he pushes back (Dave Rubin, Candace Owens), and you can see the ridiculousness of their grift. But all too often he lets it go because he doesn't know enough to challenge them on the details.
He had Bernie Sanders, Andrew Yang and Tulsi Gabbard on.
So he provides a platform for all sorts. But then it highlights what an utter bunch of campaigners the Democrats are as a whole as they turned on both Gabbard and Yang from within not because they were radicals, but because as soon as they appear to be trying to connect with all types of people (like Rogan) they turn on them.
So is it an issue when he has GOP people on but not Democrats? He actually got along very well with all three of those Democrats to the point he declared he was voting for Bernie Sanders. Has he ever declared he's voting for a GOP politician?
