There’s a big difference between Auschwitz and any of the other things listed here. No, I would not debate those in public, because the public considers them off limits. More to the point, within the context of the SDMB, which is what I have been talking about, no one holds those opinions so they won’t come up for debate. You are intentionally seeking the worst edge cases you can think of to make your point.
That said, would you read Mein Kampf? I would. I haven’t, but I will get around to it some day. Not because I find it ‘interesting’, but because I find everything about Hitler nauseating and it would be useful to see how a person got to such a place. I have read the Communist Manifesto and parts of Das Kapital, even though I think the ideas within them have caused more human suffering than any other philosophy in modern times, including Naziism.
But maybe I’m different than many of you in this. I have spent 20 years on a board full of people who hate me and attack me constantly, listening to many ideas I find abhorrent. I have never pitted someone over their beliefs, and I accept that others believe different things than I do, and it doesn’t enrage me. I feel no need to protect myself from wrongthink. I would never censor someone’s speech, no matter how vile, unless it crossed a line into threats or actionable slander.
On the other hand, some of you can’t tolerate the small handful of conservatives that might be here, and attack them incessantly. So yeah, maybe we just think differently.
