For reference, this is typically called Brandolini's law

https://en.wikipedia.org/wiki/Brandolini%27s_law

I find that dumping a false factoid that is not irrefutable without considerable work is a common tool of capitalists/fascists, just like offloading labor onto masses of workers while taking credit for said work is their way of alienating entire societies

In both cases they're having other people do the work. Fascists are lazy and irresponsible

Hanging wasn't the preferred method of capital punishment and it certainly wasn't confined to murders nor was it only used when there was 100% certainty. There's a whole religion built around protesting Rome's capital punishment.

I would say the most common hangings were the lynching of black people in the US. But even that saw competitive use of guns and automobile or horse drags. Nor was guilt firmly established prior to the given cases.

The issue with addressing it is there's too large of a surface area that can be misdirected to some other part of it.

I mean since they just casually throw it around, you don't need to disprove it. Just call it a flat out lie and Elon an ignorant bullshitter with no knowledge of world history.

Even better ask Grok to criticize it with a simple but convincing language, it will probably do a unreasonably good job of it despite its biased training.
