This is not just an issue of my child, for example, if a German user were to open that site in public, they would be found guilty of hate speech, amongst dozens of localities : https://en.wikipedia.org/wiki/Bans_on_Nazi_symbols. Also in California, where speech is free but is not free of consequences.

I don't make the rules here, I just don't want this guy to go to jail for his fun project.
