Keep in mind before the Plinkett Phantom Menace review went viral, Mike and Jay (not sure about the others) made their bread and butter doing camera work for small films. And now, Milwaukee shitlords or not, they interact on a fairly regular basis with guys like Patton Oswalt. Even Soyboy Extraordinaire Rian Johnson said something about "liking but fearing" them before he went all Veruca Salt on their TLJ review. Ultimately, though, I think they just care more about making funny shit than being the 10,000,000th ignorant moron to offer a right-wing or left-wing hot take.
I can't imagine a right wing Bob defending Hitler, but who knows? I can totally see him buying into various Jewish banking conspiracy theories and talking about how blacks are genetically proven to be less intelligent, though.
