What fucking colour is that?

Twenty has a funny post up about some claptrap of other and something occurred to me when I was reading the comments.
What the fuck are people 'of colour'? Like 'A woman of colour came in and sat down.' OR 'women of colour are WHOLEY under-represented in the blogosphere".
What the F?
What does that mean, and shut up, that's a rhetorical question because I bloody well do KNOW what it means, I just object to the expression.
I too am a fucking colour. I am pasty white with overly tan arms and tan head. I am Skewbald. In FACT I'd wager I've got more colour going on than other 'women of colour'.
Seriously, what a load of PC wank.
I am now mildly red faced. With indignation- not commonly FELT on Gingerday.
