I agree too. I think the issue just now is the realisation of how sterilised the history of the British empire has been, and how we were taught.
If by "we" you mean people alive today then I have to disagree.
I'm middle aged and I was taught at school about empire, slavery and US civil rights. Empire was most certainly not taught as something sterile. We did learn the downsides of it, both for people in other countries and in our own country.
People are fed up of other histories being erased because British people are so desperate to believe that Churchill equals hero, end of story.
I think part of the problem is that history is not a compulsory subject anymore.
Anyone young with just a passing interest in it, tends to not appreciate that history is the study of events by primary and secondary sources and that those events or historical people, must be placed within the context of the times.
It should not be something to cherry pick to prove a modern political point in a debate. This happens with both political sides tòo often now. Soundbites and short edited quotes used as debating fodder, slung back and forth
