@Bogulum,
We're taught a lot about slavery here.
We're taught about William Wilberforce and about how the British Empire stamped out the slave trade.
We're not taught much about slavery in the years prior to Wilberforce, because that's really not important.
What's important is that we stopped it.
The truth is starting to seep out slowly, the descendents of some wealthy slave owners have started to make amends but it's a trickle.
On the road to Devon there's an estate owned by a Tory MP whose great whatever was some slave dealing ****. It's obscene, it takes a long time to drive past the ******.
