lol literally 77 mln Americans voted for Trump, and I feel that what you’ve described is not a controversial take at all, at least in the UK. There is no way this would impact UK hiring though, maximum what’s gonna happen is that US firm are gonna stop advertising DEI on their websites. But that’s already happened.
UK & US DEI practices have differed. For example, US universities discriminated against Asian & white and in favour of black candidates, known as "affirmative action" or "positive discrimination". For example, for Harvard, black students in the 70th-80th percentile of academic ability had a 41% chance of admission, whereas for white students it was 5%, and Asians 4%
This was found to be unconstitutional in 2023 by a partisan Supreme Court (split 6-3 by appointing party).
This has never been legal in the UK: you can only have "positive action".
Also affirmative action was created by Executive Order (of JFK), and they seem to do a lot more on the stroke of the Presidential pen (including/excluding sex in transgender, for example), whereas in the UK a lot of these things historically came from the ECtHR (e.g., the Gender Recognition Act 2004, following Goodwin), EU as well as primary legislation (which seldom gets rolled back).
