I disagree, each of those people put on a very different show from the other or could you interchangeably listen to Ralph/Warski/Nick/Josh and get the same content?
Ralph, if anything can be compared to the AF faggots, red ice, the elephant people who I never remember their name, etc.
Just because all of the people above are "not leftists" doesn't put them in the same category, they don't even agree on most shit politically. Ralph is a race mixer who voted for Obama, wants Biden to pay off his student debt, would have aborted his child without a second thought, a degenerate, etc. Rekieta (at least pretends to be) a more Christian type conservative, I don't know what the fuck Josh is but it's neither of those, and Warski is a guy who just wants to get money for being online and he thinks the way to do it is saying nigger repeatedly and gives no shits about politics beyond that, so no I don't agree that they are all connected by a political affiliation, and the content they put out is not even close to being similar.
