Not politically correct generally refers to ideas or comments that aren't liberal/leftwing.

I'd need to know the specifics of his opinions to determine what exactly was fueling his resentments.

I could tell in a fairly short time if he actually were more of a closeted liberal/progressive/leftwinger than he may have wanted to let on.

If he does lean left, he shouldn't have been doing a talk show under the guise of his being a supposedly legitimate, authentic conservative/rightwinger.

I wouldn't have fired him, but I'd have asked, why the hell don't you come clean about your ideology?
