You are right. I don't in fact know if that's what he means by calling the Rust community "toxic".
I've never seen anything like a bigoted word attributed to Andreas, by all appearences he is one of the most caring people in open source, and his character is obviously a big part of Serenity's success in attracting followers and contributers. But he does seem to be very insistent on "having nothing to do with the issue" (of inclusivity). His stated goal is to make a welcoming and inclusive environment, and ultimately I just think letting Pixie Ada put pride flags in xer bio will be more succesful at that than a don't ask, don't tell policy that seems mostly geared to not bother people who happen to fit in by default.
This is literally the kind of toxic divisiveness he’s talking about. Can’t you see how this makes people want to have nothing to do with this issue?
