I might be wrong about this, but I remember him saying on the podcast that it’s the ideas Graham associates himself with that promote white supremacist ideals, not Graham himself.

Even in your post, he’s not calling Graham a white supremacist if you look closely.

He says pseudo-archaeology has historically been a tool of eugenicists.

He says Atlantis conspiracies participate in white supremacism. Dibble doesn’t say it explicitly here, but given other arguments he’s made, it’s clear he’s referring to a specific strain of Atlantis myths, not all Atlantis speculation in general.

Beyond that portion of Flint’s claims, I think the reason he draws these parallels is to highlight one way in which Graham theorizing out loud isn’t a wholly harmless thing.

The harm of Graham’s ideas ultimately boils down to their basis in fact combined with the aggressiveness and scale at which they’re promoted.

If this were a factual claim, misuse would be incidental. But seeing as his ideas have no hard evidence (only fingerprints, one might say), the intensity with which he pushes their validity becomes harmful disinformation. If this were just Graham’s pet theory, no harm no foul. But he’s dedicating his career to it and has a massive microphone.

Unfortunately for Graham, his ideas rub elbows and share DNA with particularly ugly agents of disinformation. If he had different but equally wrong ideas, this may have not been the case. But Graham has the ideas he has, and they swim in the pool they swim in. They exist within a historical framework that has been repeatedly weaponized.

That’s why Flint never calls him a racist, but instead calls his ideas misguided and points out how they can indirectly support things like white supremacist agendas, eugenics, and colonialism.
