I don't claim to know all about this situation, but I do discern a recurring pattern that many IT professionals don't (want to?) realise:

Information technology is giving all kinds of actors leverage to exploit our human brain's fundamental shortcomings.

In this case, it's a fscking nazi sympathiser jumping to the fore of a presidential election from nothing.

Remarkable and ironic to me, these actors weaponise the powers of technology while often spitting at the scientific method underpinning them.
