I’m shocked at the level of ignorance and fear demonstrated on this thread.
The fact of the matter is at least 90 NT properties are significantly connected to slavery and colonialism. This was the source of the wealth that allowed them to be built and maintained. For instance, if you are unaware look up homes built by the “nabobs” returning from India. Sure, some visitors’ primary motivation is simply to have an ice cream rather than actually learn something. That is their prerogative. But it would be ridiculous not to tell the story of a property’s construction. It is exceptional wealth that made these homes possible and it would be ridiculous to not tell the story of where it came from.
One way of thinking of what the purpose of history is, is to tell us the story of how we got to who we are today. And as who we are changes then this story should evolve. As Britain becomes more diverse then it is right that we should place more emphasis on the story of where this diversity came from. And this, of course, includes the stories of British involvement in colonialism and slavery. If you still don’t agree consider this: when NT properties first opened the stories of servants were under-represented. Now it’s normal to tell them as we understand the connectedness of these properties across class. Telling stories of their international connections is just the next step in a more accurate history, which is also more inclusive.
As for LGBT+ stories, reading the posts here one gets the impression commenters think homosexuality was invented in the ‘60s. There is a rich history of same-sex sexual behaviour going back centuries. Again, telling it is just surfacing a fuller perspective on the past, not fashionable “shoehorning”. Yes, using todays identity terms might be in danger of being anachronistic, but this can be overcome.
I suspect those objecting feel threatened by more diverse historical storytelling feel threatened as they feel the history that they identify with - that, in part, constitutes their sense of self - is being eroded. This is a well documented phenomenon. But it has always been so. History is not discovered it is produced. And new generations write their own histories that need their needs better.
