The greatest damage we’ve done to speech is “everyone” agreeing that “we must, of course, ban hate speech.” Hate speech has no definition, and no one but those seeking to control you, gain anything from limiting hate speech. Everyone should want ALL speech protected. If someone wants to cause you harm, shouldn’t you prefer that be made public so it can be monitored and investigated? This idea that some speech is okay and some is “wrong” is exactly the slippery slope those who wish to remove your liberties desire it to be.
