I think you are wrong to see this as purely political. Women being portrayed as nude, battered, covered in semen, and so on are genuinely horrified. Such images would not be tolerated if they were sourced from a political ally.
Furthermore, I don't think that fake nudes of the US President are morally equivalent to fake nudes of minor public figures who are 99% women, even if the law treats them the same. We need to take into account the completely different lives that men and women online experience, where women are constantly subjected to sexualization and abuse.
This is one of those topics that discussion on HN is hopeless because women are so underrepresented.
They aren’t tolerated on X, people get banned for this. That’s why the whole thing is so duplicitous. x is not different from other platforms in this regard. Grok on X was also limited to paying users because of this.
