One would hope that social progress means that people learn inclusiv[ity|eness] as an abstract ethical concept and, from that, language and other social practices follow. Instead we're down a route where we're force-fed a kind of saccharine social justice orthodoxy that can only have two outcomes: hypocrisy or backlash.
I think the previous generations of leftists achieved their goals of inclusivity but now that we have it, it turns out it didn't eliminate wage gaps and all that so new leftists have decided we need to turn it up to 11 instead of stepping back to figure out what's actually causing those differences between groups. They can't allow themselves to consider that it might be something other than sexism/racism because that's an existential threat to their ideology. So the only way forward is ever more aggressive "inclusiveness".
