Earlier quoted context omitted.
This is not how we did things in the 90s we used to debate these speakers and knock down their ideas with rational discourse it's not that hard to deflate the arguments of the far right they're mostly based on a series of bad assumptions like assuming everyone has a deep fear of anyone who looks different than them. It's better to let them speak and then deflate their arguments to the bone in debate.
That's what we did back in the 1860's too. There were all these people who wanted to build an economy based around the idea that some humans didn't really have rights and so we deflated their arguments with rational discourse. Obviously I'm not comparing teachers of Western history to slave owners. But i am trying to point out that rational discourse alone doesn't yield a more egalitarian world.
Any idea can become evil when taken to an extreme.
