May I say that "raising the left hand" seems a little sinister to me..
Re racial slurs...
Officially in Australia being called a Pom in not a racial slur, but being called a "pommy b@stard" is!!!, as per a recent court ruling.
and you get national news readers over here saying Australia beat the "Paki's" at cricket, but its not said in a negative way, neither is "COON" cheese (yes its a real brand name) what a fantastic country!!
There is a small annoying few who try to drag the "pom" word through the courts to try to outlaw it... they are the problem, as it transforms the word from a somewhat dubious compliment to an outright insult..
In short - get a life... We don't need racial slurs to start a fight, as just punching someone can get your point across.
BTW Its hard to type with the left hand up... when can I put it down?
Cheers
