Give up on the pasty thing. It's not a racist/racial slur. Imagine a couple of girls going on holiday. You're sitting on the plane behind them and one says, "God, I wish I went on a sun bed before flying out...I look dead pasty".
Would you be shocked at that?
No you wouldn't, because it isn't nor has it ever been a racial slur.
I assure you that if asked friends/colleagues, they wouldn't agree with you.
In fact, I've just taken as straw poll at work (five people around me) asking them whether they would take offence if I referred to them as pasty. The only one who said she would explained that she's just had a course of spray tans and it would mean that she'd wasted her money.
Pasty and sooty are absolutely not 'the same thing'.
