It's his attempt to poach the more extreme audience outliers from Tim Pool, at the very least to make his "brand" more distinct from the other MAGA slop.
To even entertain the idea that Jer is some kind of radical is laughable, he cares about simple cash flow and his ego, that's it. He wants to wallow like a sealion, doing the least amount of work possible, making a profit in the least mentally taxing way possible.
If the political table dressing of America were arranged differently, and one could be a Marxist/Socialist influencer, act like a pig online and make an income, Jer would be using Communist buzz words instead of MAGA buzzwords.
Jer cares for Jer, Jer is a busy idiot, Jer would stop being MAGA if you had to walk 2km a day to be MAGA, Jer is the kind of guy who would immediately defect to Aliens in the Science Fiction Movie.
