How about the English? I'm a second-generation 'white' American citizen. My grandfather was a Canadian citizen from London, Ontario who migrated to the USA in the mid 1920s as a boy. The English, largely due to the influence of Wilberforce, passed the Slavery Abolition Act in 1833, which outlawed slavery in the British Empire and predated the American Civil War.

I mention this only to support the point you make above, not to virtue signal. Anyway, it's nothing my family did, it's just historical circumstance. But to my family, the insane amount of politics and drama around DEI and BLM in America still seems foreign to us, even a few generations later.
