SSC is/was golden.
It was one of the (very) few places where you could actually hold discourse, and could actually disagree with one another.
One interesting measure of a site is how far of an outlier your views can visibly be while still being welcomed and discussed, and SSC was the winner on that metric. By far.
I'm suffering from SSC withdrawal already.
They do have two subreddits, but I have no idea how welcoming they are. The_motte and SlateStarCodex.
I already know about those, but thank you.
There's a strong distinction between "no-one can say another person's view is incorrect" and remaining calm while holding rational discourse in the face of disagreements. They are both "welcoming" in some sense; the latter is what I'm looking for.
SSC is/was the latter; the subreddits were both leaning toward the former from what I saw before I left.
I'd like somewhere where someone can go "yes, given these axioms that's valid logic from there" (or "no, that's invalid reasoning given this value-set and here's why") without going "I don't hold these axioms so these axioms are WRONG, end of story". If that makes sense.
