I'm rather partial to you too moondog. I hadn't heard about the Welsh knot. It wasn't me though, honest.
You're right. 'Racism' is the wrong term and lazy of me. It a smilary sort of bigotry though.
I have heard all about the Highland clearances and Culloden as remeber sinking into my chair in history class several times for fear of being personally blamed. I was taught, along with my classmates, to hate the English.
I now have a fuller understanding.
It wasn't 'The English' behind this repression, it was the English landowning class. English peasants were forced off the land by the enclosure acts and ended up as wage slaves working up to sixteen hours a day in dangerous factories and mines. Many more millions of English peasants were beaten, disenfranchised, transported to the colonies, hanged and starved to death by their own upper class and used as cannon fodder for colonial wars.
This is something which I didn't learn in history in my Scottish school.
As for the Highland Clearances, two thirds of the landowners responsible were the existing Scottish landowners looking for a quick buck from the new farming methods and willing to sell out their own people for cash.
Culloden in the minds of the English redcoats fighting at the battle was the culmination of almost a century of continual Scottish invasion of England.
1648 - approx 60% of Charles' army was Scottish and 40% French mercenaries.
1715 - A full-scale invasion by Scottish Jacobites.
1745 - Same again. Result, Culloden.
I don't think anyone comes off smelling of roses but IME the English don't hate the Scots like the Scots hate the English.
