'Coloured' and 'Negro' were the polite words in my youth (50s and 60s). I never heard anyone refer to dark-skinned people as 'Black', it was regarded as rude and insulting. I still (in my mid-60s) find myself instinctively wanting to use 'Coloured' when describing dark-skinned people.

Which prompts me to ask - why is it OK to describe a person as being 'Of Colour', but not OK to use the term 'Coloured'?

It's a minefield out there to us of the older generation!
