OK, so it's an American study but 11% of all adults and 20% of millenials in the US haven't heard of the holocaust, or aren't sure whether they've heard of it or not.
Given that this is one of the most important events of the 20th century isn't this simply appalling? How can people NOT know??
I'm not aware of the curriculum in the rest of the UK but I know my secondary age kids in Scotland have learned about the Holocaust as part of a WW2 topic, and it was touched on in RE too when they learned about Judaism.
And quite frankly if it wasn't in the curriculum I'd be making sure they knew about it as it's such an important event which should never be forgotten.
