@OchonAgusOchonO no insult intended I assure you.
I think your characterisation of my list as bringing enlightenment to the savages is a fair one. However, and I think this is crucial to consider in this discussion this very much includes the savagery within ourselves. Which I appreciate wasn’t the perception at the time, or indeed even now from some people on my side of the debate.
I would agree with you if you would challenge the notions of racial superiority that riddle the very notion of Empire, which is one of the many reasons why it’s a good thing we have moved past Empire.
You are of course also quite correct upon pointing out that the countries that unshackled themselves from the Empire peaceably did so because the financial benefit had expired, but again one of the reasons this could occur was progressive advances in economic theory shifting both our Empire and by extension a lot of the rest of the world away from Mercantilism (which is the very economic practice that underpins and drives empire itself) towards free market theories, again very much a product of the British Empire.
I will however fiercely stand by assertion that we realised slavery was a great moral evil, challenged it and upended it when it was not in our economic short term interest to do so. The reason why I am committed to this point is not primarily to lionise the British, it more points to the fact that large societies can in principle act against their own self interest on ethical grounds which has relevance today in the sphere of environmental discussions, as well as others. Thus carries relevance today.
The other point you raise I’m keen to address is what might these other cultures have achieved without our interference? Well we will of course never know, but empirically looking at human societies (and even other Empires for that matter!) generally I would have predicted an awful lot of wars, suffering and death.
Human history was and indeed is sadly still replete with a lot of atrocity, murder and hate. Whilst I appreciate it is the fashion to scapegoat things like the British Empire for these all too common human failings, I do not believe it is cognitively dissonant of me to take pride in my culture’s contributions in moving us all away from such things as well as giving fair reflection to the times we have given into those darker impulses ourselves.
I also think we would all derive great benefit from a wider study and appreciation of world history/culture, as there is a vast richness to be found in all corners of the world.
