It’s a shallow understanding of free speech and expression, not to mention argument, which believes that every issue has eternal value on all sides. Society doesn’t suppress the flat earth view of reality by ignoring it, because it’s been addressed and destroyed. Life is finite, and too many are happy to waste what time we have on craziness or hate, and we have no obligation to meet them halfway. If there was some new information in the debates over race in the 60’s, then your point would stand. That wasn’t the case though, and there was nothing to suppress except a persistent, ancient, hateful ideology. This is true in the same way that balanced reporting shouldn’t boil down to giving a scientist explaining why the Earth is round, with a lunatic who thinks it’s flat. They’re entitled to their beliefs, and tell them to anyone who wants to listen, and we’re entiteld to ignore them like they don’t exist. That’s not “suppression” in a meaningful sense.
