History has told that lesson a thousand times.
Still, there are ever new people that seemingly lack the capacity to recognize the lesson (my guess is, the minority), or, for arguments sake, chose to ignore it (my guess, the majority).
That’s because it’s a garbage argument disproved by exemple.
Most of Europe has strong law regarding hate speech and didn’t devolve into an awful fascist tyranny. A free country doesn’t have to tolerate everything.
Meanwhile their allegedly incredible laws didn’t stop the USA to conduct kidnapping, jailing without trial and for indefinite duration and torture of dozens.
