I'm strangely reminded of one of my favourite scenes from Citizen Smith. In the local pub, Wolfie's just had an altercation with a blazer-clad posh boy and had to back down. Wolfie turns away.

WOLFIE [sotto voce]: "Ponce."
POSH BOY [in tones of offended dignity]: "I didn't hear that!"
WOLFIE: "Oh." [sotto voce] "Deaf ponce."

All you're doing at the moment, David, is promoting yourself from the 'racist' category into the one marked 'dishonest racist'.
