No they’re not. Kimmel has said way worse shit about Trump and republicans than Barr did about Jarrett. Who actually does kinda resemble a primate incidentally. In reality Roseanne was being more truthful than Kimmel.
That said, Kimmel’s dumbass fantasy about the shooter being right wing was no worse than shit we saw here or for that matter any number of ridiculous assertions the cows on the view or that Rachel Maddow dude have made over the years. It is rare to cancel a show over someone spinning politics, even if it is blatantly bullshit. I mean Adam Schiff spent a whole year lying through his teeth and they made that piece of shit a senator or something. And it isn’t as if Kimmel was making vile personal comments about Kirk like a lot of the left did.
Either way they are both examples of networks trying to save face when one of their employees say unpopular things.
