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".
