Thanks for the perspective Chris. I didn't appreciate the other parallel coming from the segregation of 'coloreds' back in the sixties.
There was something on BBC Radio 4 this morning about one of the Scottish ports receiving black American sailors back in the early 1960's. When on leave, they asked a surprised Scottish bar tender, 'where can we sit?' IOW's how is the bar segregated?
Amazing to think this was only 50 years ago.
