Yeah that’s not actually incorrect too badly. Well perhaps the “bound together” bit but like history for the massive systems, yeah, it is somewhat shared. Common law and whatnot. Although Italy definitely doesn’tuse common law anymore so Trump would be better of comparing US to brits in that sense.
I doubt Italy ever used common law as that originated in Medieval England. It’s civil law that descents from Roman law (specifically Justinian’s codification of it). Since civil law is way more common around the world most countries have more in common with Rome than the US (or other Anglo countries) do.
You are right however that trying to portray the US as a modern ‘Rome’ is not a Trump thing but common American propaganda.
No, it was not clarified, they vaguely mentioned they were not based in “free speech” US but it’s pretty clear that it was their own policy since they changed it (they do say they were asking mods to ban all mentions of jury nullification).
If their opinion was actually based on law, they would not change their policy. They would probably also have added it to their TOS before hand.
