Pre-modern societies often took words very seriously. The Romans didn't have a robust sense of being arrested, per se, but purely verbal harassment and threats were treated the same as physical battery that didn't cause permanent injury - as a cause for a lawsuit and fines/damages to be taken from the offending party.

You could be drawn and quartered for saying the king smells bad. Protected speech among the common folk is a very new thing and relatively rare even now.

My opinion on it, from what I understand of terrorism, is that it's lasted for the past 5,800+ years (ever since the creation of our planet), which started with Cain taking down Abel, for Abel had a better gift to Yah than Cain.

The evolution from hurtful speech to something being a crime is because of the evolution of pre-crime (KYC was the start of it), which started to accelerate back in the 00's with the PATRIOT Act in the United States (the District of Columbia, the city-state it is), though it was some time earlier. However, hurtful speech was supposed to be protected since America had its start, though I later found out that 1A protected practicing Catholics, and completely ignored Protestants (making the latter slaves to the former). As long as it's "lawful, but awful", then I think you should be alright.
