I don't see your point. Unless they're sending him money (an idea a number of them have mocked), they're just posting on his site, mocking him and get more willing to give him the Lowtax treatment every day. The only thing keeping Null from getting treated like how Metokur gets treated on Twitter is that he's willing to destroy the forum if it comes to it.
Josh would need to actually like politicians or political candidates to donate to them. He obsessed over Vivek's primary opponent but then dropped him like a hot potato the minute he said something nice about Josh's personal enemy Nick Fuentes. He hates Trump because he lets in too many Indians (but will never say it because the Trump worshippers are his only friends now). He hates political charities too like the EFF. Josh would only donate to a politician if a personal enemy were running for office and looked to be winning.
