> Of all the things to complain about Musk, this seems like the weakest.

I would argue it's the strongest.

"Pedo" is one of those accusations that sticks around associated with your name, often even when it's false.

Knowing that, Elon Musk, one of the best known people on the planet at this stage, called this to a real person. This can ruin a person's life. Did he have any evidence, even circumstantial? Nope. Did he have a reason for this attack? Only that he felt slighted.

So Elon Musk is ok with potentially ruining someone's life if he even as much as feels slighted.

I think even is the strongest hint of what his character is like. And character is, you could argue, the most important predictor of future behavior. I took this hint of character at face value, and after that I've never been surprised when I've since heard accusations of fraud or sexual harassment. No surprise whatsoever.

So if your reaction to this is Elon Must has potty mouth, you're either breathtakingly stupid or dishonest.
