Okay, so: I'm white! A white, professionally successful, functionally very upper-middle-class but from a very rural working class family woman, actually (and, yes, this all sort of matters):
Here's the thing about the diversity markers situation: SOME of this stuff is actually very valid. Such as, frivolous as it may seem, the "wearing 2nd hand and swearing" thing. You see, I don't sound rural working-class. That'll be because I won a scholarship to a naice school as a child and speak as though I could trace my family tree back to roughly around the 9th century. Which I most certainly can't. It's just that "oh, do fuck off, dear!" out of my mouth, spoken in clipped RP, comes across as a hard but surgical strike of a reprimand. This works neither for my British black working-class subordinate (taken as "uncultured") nor for my much more "cultured" (can actually trace his pedigree) but very German boss (taken as "2nd language speaker who hasn't quite grasped the nuances"). Same goes for dress codes, by the way: in the corporate world, you can turn up in basically anything, so long as you're the sort of person people will assume does it due to individuality or arrogance rather than not knowing any better. My "personal best" happens to be "yoga pants - for a contract negotiation". Underdressing is, genuinely, a way to posture and outwardly signal "power". If you are a person who already has significant power, that is! Nobody will invite you to a negotiation over millions without assuming you own plenty of suits - and you turning up looking casual is an effective way of saying "this is small-fry, I haven't even bothered to dress up for this" and hence: negotiating tactics.
Having said that, I generally tend to agree that it's all a bit silly - and I'm steadfastly refusing to do pronouns on the grounds that I happen to think it's all vapid virtue signalling. But, then again: privilege is real, I have it (except on sex) and that is precisely why I get away with it!
No harm in a little self-awareness here and there!
