There were multi-generation serfs and indentured labour in the British isles. There were also slaves taken from the isles, though a very long time before then.
Slavery was never lawful in England, though it existed. Obviously it was allowed in the colonies. (Before anyone bites my head off, yes England did benefit massively from the trade, and its legacy persists in eg placenames in Bristol etc - I'm just answering parent's query)
There was substantial indentured labour and serfdom in England too. Surely simple redistributive tax based on wealth is fairer?
Anyway how do you determine whos ancestors had slaves, or weren't involved, or were slaves? You want to start tracing bloodlines?! Should the English pay the Irish?
This is an example of the American cultural imperialism someone else was whining about above.
In the UK a f@ggot is a type of food. There are adverts on the telly for it. A fag is a cigarette. Gypsy is not necessarily perjorative (it appears as a category on the census).
Not sure what tr*p is, but if it's tramp, that's a homeless person.
Also, a fanny is ladybits.
In the UK squat toilets still get called French-style despite not beong found in France for generations.
