When I was a history student in the UK most of the classes I took had some degree of racial undertones (one class was literally just about Racism in the UK).
The main thing I learned is, while it feels natural to compare UK racism to US racism there is, in reality, very little to compare. The demographics are different, the history is wildly different, the underlying cultural attitude is different, the political system is incredibly different.
Does anyone think a candidate named Rishi Sunak (MP from rural Yorkshire) would win a congressional seat in rural Ohio?
No, if only because the norms around parachute seats are very different.
