I gather by the bijection comment he meant the discussion about equivalence classes on R that have more elements than R.
Also I've never took a course in set theory, it's just a topic where people have often problems wrapping their heads around things and so you can explain things in a sentence.

Nobody on 4chan (probably also not discord, for the most part) puts in work of working things out for other people (since often, when you do, the OP wouldn't respond anyway and you might as well talk with a wall). So it's mostly chill banter. (And yurakari or what's it called overshoots in an annoying way where he just uses the questions to rant about vaguely related things he takes and interest in.)

I'd argue the opposite is the case. In 2015-2018, I felt there was a lot of light category theory mumbling.
