I share your experience that I've not encountered many with these conflicted feelings, but I'm not sure about the educated bit. I meet a lot more working class lads with the attitude of ^'I am who I am. Fuck em if they don't like it.'>
To me it seems like there's a lot more hand wringing from the middle classes. Like how we're always told it's the ultimate sin to ask where somebody is from. I just don't see this in real life. I actually find that a lot of non-white people are a lot more likely to ask.
Like, I've been training up a Ghanaian guy the past fortnight. Lovely bloke. He moved here as a child in the early 00's and has lived in Belgium, Amsterdam, and all over the UK. Always asking questions about heritage etc. Am I Scottish because of my red hair and surname. Why don't I have a Scottish accent if I'm of Scottish descent etc. He's always pointing out other black people and explaining he can usually tell where they're from by their appearance. Somebody was rude to him onsite the other day and he said he was particularly annoyed because the guy was Portuguese and 'same as me, looking to make a life in this country'.
I still tend to err on the side of caution at first, but really so much of this middle class hand wringing and wokeism, doesn't seem to usually be a thing in the real world, well not outside of overly ethical corporate environments like the law firm I once worked for which literally had a 'no banter, banter can be harmful' policy. I've found mist people like it when people are interested in their background.
Apologies to have gone on a bit of a tangent.
