I can't speak for anybody else cuz I still have some major issues with Rogan and generally don't fukk with him. But you're attempting to do what every other Bernie bad faith critic of this whole silly Rogan ordeal has done. That is pretending as if Bernie has done anything whatsoever to change his stance or platform to appeal to Rogan or his listeners. He didn't go on his show and pander, talk about hot sauce, his weed smoking relatives, his favorite submission holds, shyt on immigrants, or anything every other politician does when given these types of platforms.
The only thing I've taken from it is that it's a good thing that Bernie's message was amplified, and if Rogan endorsing him gets some of his followers to educate themselves on why Bernie is the best candidate, then great.
I'm not particularly thrilled at his camp amplifying the endorsement though. Not in and of itself, but you can't big up Rogan who has had Gavin McGinnes, Milo, Crowder, and the usual dark web alt-right clowns on his show unchallenged and credited endorsing you if you just shyt on Cenk and tried to distance yourself from him for some shyt he said well over a decade ago when he was a Republican.
