I’ve heard a lot about that programme A House Through Time - I think I’ll give it a watch. I don’t remember learning anything about the slave trade or any of that stuff at school - mind you we had a crap History teacher who would have sent anyone to sleep. We had a great one in third year who really livened up lessons but then I dropped History after that :(
The protests have definitely come at a bad time - it’s very likely we’ll get a second wave of the virus from that - but I, too, can understand that expecting people not to react because of lockdown was a bridge too far.
