BSL: Mind Your Language

Political correctness has caught up with Britain's deaf community. It is no longer acceptable to sign a slanted eye when talking about the Chinese or to mime a hook nose when referring to Jewish people. The flick of a limp wrist is now an offensive signal for homosexuals. A finger pointing to an imaginary spot in the middle of a forehead is no longer appropriate as the sign for India...
Their sign for a Jewish man or woman is a hand resting against the chin and making a short movement down, in the shape of a beard. A gay person is indicated with an upright thumb on one hand in the palm of the other, wobbling from side to side...

The Guardian online.

Ackhually, I think the old school BSL sign for "gay" wasn't meant to be a limp wrist, the drooping hand - with thumb pulled back, and often put on the head - was meant to represent a crown for "queen". 
Some of my best friends are deaf etc etc.

Update: Turns out much of this article was balls. 

PS Also, while we're talking about acceptable language, why is The Guardian using "homosexuals" here - it's proscribed in your style guide (p. 128).
As is the silly right-wing smear term "political correctness" (p. 232).
