Breitbart has been garbage since forever. I don't give a fuck that he quit, the fact that he was there in the first place is telling, and notice how he didn't quit over ideological differences, he quite because one of his colleagues got fucked over by Bannon.
Cool, that doesn't change his garbage arguments one bit.
I said he's either a disingenuous hack, or he's an idiot. It's true that I lean towards the disingenuous hack explanation but I left the door open for the alternative.
You should check out his book "True Allegiance", I came across some excerpts which were hilariously bad. Every fucking stereotype and conservative bogeyman he could think of he shoehorned in there, it's actually some of the funniest shit I've read.
