Honest question from a non american. Who is Joe Rogan? And why is he a persona non grata? And what is his relation to Jordan Peterson? I'm seeing a weird attempt to link the two in the media (presumably as an attempt to use the former to discredit the latter) but I've never even heard of Joe Rogan except in the context of trollposts (which usually do not give the necessary background I need to know what's going on)
