See though you’ve got it backward. We’re at the point to today where literal propagandists like Bannon, and conspiracy theory sites like Breitbart and Infowars, are reaching the White House and influencing policy. You’re worried that someone somewhere is going to call someone a Nazi to silence them when we literally have the election of a grossly unqualified man on the crescendo of 30 years of virtually nonsense, propaganda and slander. Sean Hannity has the highest rated cable news show, Fox News posts 2x the numbers of CNN.
And besides Scuzz is talking about college campuses. Should we give Kid Rock a lecture to teach kids about civic virtue, Sean Hannity one to help inform kids about how Everything Wrong In America came from Democrats, maybe invite Vladimir Putin to teach kids about Democracy? We’re seeing firsthand the marketplace of ideas theory doesn’t actually work. You can’t expect every single fact to be fact checked as a matter of course. Lies and propaganda repeated have an anchoring effect. The outsized influence of Facebook memes on this election only proves that.
There should be a threshold where you simply don’t have to contest point by point but toss the speaker and their unfounded ideas out the door. If not, good luck convincing religious people the world is more than 5,000 years old and evolution is real as you spend the rest of your life arguing point by point against a tidal wave of anti-scientific nonsense. You don’t expect universities to sponsor lectures on how the moon landings were faked or that the Grand Canyon was carved by the hand of god. It is possible to say certain ideas are beyond the pale. Once you admit that, all you need to do then is argue where to draw the line. If for some reason you still think “well, genocide is bad but let’s hear what they have to say out of principle” you also get to listen to why essential oils are a great idea, vaccines kill kids, the earth is flat and chemtrails made you vote for Obama.
