Although no where near as bad as it was...Sectarianism is still pretty big in certain parts of Scotland and was huge in the 70s and 80s. In terms of race, Scotland today is pretty diverse but it apparently - through word of mouth from relatives - was pretty traditional. English and Irish people today still suffer from some segregation, but only by a very small narrow-minded minority
Not just against blacks, but against Highland Scots, Irish, Italians, and English. The first racial lynchings were in Glasgow, 1919. Discrimination today in common in Scotland, especially in the south. The Highlanders were also severely discriminated against. I think for these reasons, while American Jim Crow tends to get the most recognition, Scotland had their own segregation.
