I dimly recall the posts that were deleted; when I read them I couldn't help thinking that we should reflect on the effects of the British Empire that we are feeling, and so many people are disliking, to this very day.
We took over so many countries, we ruled them directly, or indirectly through client rulers who complied with our laws and elite structures. We plundered their resources and drew their wealth into Britain. We treated their native populations as inferiors who existed to serve our wealth acquisition.
Or we sought to control them as a pawn in international relations. Our troubled association with Afghanistan stems from the mid 19C attempt to use Afghanistan as a defence against feared assault on our Indian 'possessions' by Russia.
But, above all, we told them they were British. That Britain was the 'mother country' of which they were citizens. We used that trope to enlist them in our armies. Dinahmo talks of WW2, but in WW1 we had West Indians and Indians fighting for Britain (and Australians and Canadians, but no-one worries about that because they're really 'just like us').
Then, when these 'British' subjects came to claim our protection (think Ugandan Asians) or when asked to fill our labour gaps (think Windrush), we treat them as second class beings and eventually repudiate them by taking away what they thought was their automatic right, as British citizens, to come to Britain to live and work.
I think we have to live with this and accommodate it. Blaming them for the problems Britain brought upon itself is unfair and shortsighted. We can't make the consequences of our Imperial past just vanish.
