HBomb, as well as Shaun (and Jen) and Contrapoints, was just in the right place at the right time with left-leaning content. He was dunking on alt right weirdos when they were surging in YouTube's algo, and thus was one of the first big names in the Breadtube phenomenon, which could be seen as a reaction by progressives against the right wing domination of the platform. "Breadtube" has of course grown and changed in the meantime, and I don't think HBomb claims the label, but he was riding the wave of it whether he intended to or not.

He's pretty far down my list of lefties at this point. He makes good videos but he's basically avoided talking leftist politics or even dunking on right wingers for a long time, although I'll say that his stream for the trans youth charity Mermaids remains a legendary online event.

If you want to see his best content, I suggest you scroll back to his videos dunking on The Golden One, Sargon of Akkad, Thunderf00t, and Pick up Artists. IMO the longer and more well researched videos he does now aren't as good and cathartic as the thirty minute ones he got e-famous with.
