Just a quick reminder, Welch uses they/them pronouns.
I'm skimming over the forum messages because I find that I agree with a lot of points Welch talked about so I'm not super interested in discussion, but, to clarify a few things I've seen: The transcriber transcribed it as "no lollies" but they said "no lolis". Lolis (or lolicon) refers to a manga/anime archetype where characters who are or look like underage girls are sexualised. So yeah, it was pretty rational to say there shouldn't be any in a game.
The scene where Astarion sleeps with you in act 2 is pretty well described in the talk, basically you ignore what he's telling you and say you want to sleep with him, you do, and then he breaks up with you once he realises that was a horrible thing for him and that you made that terrible choice. If you have the heart for it and aren't triggered by that topic, it is a great poignant scene. It's very painful but I was in awe at the guts it took to write something like this in a videogame, or rather, a (soon-to-be-done) romance.
I'd also say I find analysing what Welch is saying in this talk to redirect it into AA discourse (which they didn't go into in this talk, at all) to be kind of in bad faith.
