From what I've seen of some of my Gen A kid's online group chats, if it comes up (which is rare), 'identifying' as anything is largely met with derision and/or mirth. They are talking about third or imagined parties rather than anyone in their contacts. They're a pretty clued up bunch, from what I can tell.
I wonder if these kids are bored of it already, see it as unfashionable and are going to be less susceptible to the ideology (and indeed any belief system)? Or they just don't know about it yet (which is encouraging in itself tbh).
