Half of the US has been told to not follow the news.
Hacker News is a news site so I imagine little to no one on the Trump train is here.

That is to say, the US attitude towards free speech is not somehow the result of some very wise collective, it simply hasn't had the history to affect its attitude towards it in the same way that European countries have.
Ask a Native American (or one of dozens of other groups whose vilification enabled their oppression and murder), or maybe read a history book? We Americans aren't less experienced than Europeans; we're just more committed.
I think you may be right that ethnic genocide alone may not be enough to change a whole population's opinions around free speech rights, that there may be additional factors required such as general awareness of how bad it was to engage in such acts and what contributed to those acts.
Free speech protections weren't obviously relevant to the genocide as it has occurred, although it wouldn't surprise me to learn e.g. that a native counterpart to Frederick Douglass had been silenced unfairly. As for speech in the other direction, the worst things were said (and done) by the "greatest statesmen" [0] so I doubt that corporate speech codes would have been much help. If it isn't too presumptuous of me to observe, it's unlikely that such things would have done much to slow down Hitler or Mussolini either.
