I think they mainly have an issue with idiots and hypocrites. They are fans of RFK Jr, Tulsi Gabbard, and lots of others; they also slam lots of republicans as well (for being hypocritical idiots).
The concepts of "Trump being a uniform piece of shit" and "Trump being the target of a weaponized judicial system" aren't mutually exclusive but he can't seem to reconcile that fact. I like to think it's because he has an appreciation for Trump's genuine skill at showmanship, but I tire of it.
There is inarguable value in the twice weekly media roundup that they do, so long as they stick with mainstream sources and stay away from silly medical blogs and Cuban ex-CIA guys. No one is perfect I suppose.
FWIW I don't think either of them are any sort of bigots, but sometimes old school chauvinists and maybe xenophobic in a way that makes you groan but not particularly offensive. I hear way worse daily on my university campus. It's the criticisms that they shy away from that make people irritated, I think.
