There are words that were once considered OK as descriptors of people, which are now no longer considered acceptable in that context.
Coloured is one of them.
For people of Afro-Caribbean origin, we use “black”, etc.
However, if you go to sub-Saharan Africa, coloured has a very specific meaning, and can – in certain circumstances – be the most derogatory descriptor.
Frankly, language changes and the imputed meanings to words also change. I tend to take the view that certain things are probably more offensive than others, but just try my best to keep up with what’s in and out and tread carefully if I don’t know.
If I don’t like someone, it’s not because of the colour of their skin, religious beliefs or ethnic origin.
And no, none of this is PC gone mad.
