My experience of prejudice in the 1960s was when we went to a department store with a Trinidadian friend to buy some sheepskin gloves for the cold English winter. My friend had large hands and none of the 'women's' gloves fitted, so we asked to try the men's gloves. The sales assistant was very reluctant to allow this - presumably it would have meant she was a transvestite.
I can't remember any discussions about what she should be called, other than Trinidadian.
