I expect most of us grew up watching tv, drama, films etc with largely if not totally white cast
The first black people I saw in real life, weren’t GI’s I saw walking in a group in Padgate, a village near Warrington with a USA airbase. They were separated from the white GIs. I was 8, look mummy, black men. No, don’t say black, that’s unkind, say coloured people - said my kind mum, trying to influence me to a more gentle description
Life is very different now than in the fifties but the dominance the white privilege is still with us
