I have watched reddit become useless for any kind of nuanced debate over the last 5 years. It's rather sad to me, because once upon a time I learned a lot about others views - especially ones I disagree with.

Even HN is much less welcoming of the "I think I agree with you, but walk me through your thinking" replies than it used to be.

I presume this is reflective of a few broader societal trends, and it's.. not good.
