It's complicated and I can only be very 'broad-brush' here, so apologies, but by revisionist I mean...sure, the Ladybird Book view of history is clearly not one we would be satisfied with as well-informed adults, but I think we can go too far in being negative...even nihilistic about our history and I think that's not only wrong but very harmful to us all.
I think some people have taken it to such an extreme that they view (and will teach children that) the history of the UK as one long catalogue of shame. If it is, then I would say - that could apply to pretty much any nation. The big issue currently is slavery, and the issue I take with that is that I was taught about the slave trade long ago as a child in the 60s/70s, both at primary and secondary school, as well as watching TV programmes about it, and never at any point was it portrayed as anything other than horrific and morally wrong. I don't think it was ever hidden or covered up - at least not in my educational experience. But, mysteriously to me, some people seem to have only jut heard about it and it now dominates all discussion about British history.
In fact, slavery is common to pretty much all dominant cultures throughout history (Ancient Egypt, Greece, Rome, pre-Columbian America, all the major European powers in the age of empires, the States). Some might argue that it still goes on in places like Dubai!!! Certainly it was practised in Africa even without the intervention of Europeans. It's horrible, but the British didn't invent it!
While acknowledging its horror (as, incidentally Prince Charles advocates - eg teaching it as the Holocaust is taught), I think it's important to teach children about the positive aspects of their countries history too. I just don't understand the relish some people have to rubbish everything about their homeland - so strange! There is so, so much to celebrate, in fact.
