That will be a huge culture clash there. Current servers have a very anti-SJW population. WoW classic really is a classic game. I expect to read lots of angry Kotaku articles, haha.
The schools are where they are polished and shaped, with a tiny bit from parents - if they even talk about these things with their children anymore.
If in the future we see "anti-swj" be the norm we could say that "well, we saw it in barrens chat". Similar with 4Chan back in the day and probably still now.
I wonder if there are experiments going on using the data from ancient game chat and IRC channels (and so on) to verify this, and to check whether we can predict what may happen next.
One scary part is some people may consider this as yet another platform and opportunity to manipulate and control the minds of the future.
