I'm not a fan of filter bubbles either, as the term is normally defined, but I'm comfortable with the idea that there are limits to the things you can believe and still be taken seriously. If you non-ironically believe that the Earth isn't spherical, and that there's an "atmosflat" rather than an "atmosphere", I'm comfortable disqualifying your science takes. So it goes with The International Jew.
I don't have a better source! If this source is actually good, rather than someone, again, doing the thing Orson Scott Card so notoriously did, of fanfic'ing international politics and military conflicts, that'd be a good thing to point out! Is it?
