It is! But ironically, section 230 of the DMCA has probably been more important for enabling communication platforms like this one vs other western countries that also have free speech protections similar to 1A

Anyway, Europe's speech laws vs 1A isn't what's stopping social platforms in Europe. Lack of DMCA section 230 is

Main difference is you can't incite against groups, and even that sometimes gets overridden if speech has political/religious value. A pastor in Sweden got acquitted for saying gays were cancer because religious protections outweigh incitement laws

Otherwise, it seems like a subtle difference in imminence (UK arson incitement would be illegal in the US too if they added "tomorrow")

No other country comes close to 1A unfortunately
