Just thought this might make an interesting debate,and no offence meant.
When you see someone you know maybe in the distance,where I was brought up you would raise your arm,palm pointin toward them,this could be likened to a nazi salute,and as such some daft countries in Europe have banned this,you couldnt make it up, honestly its PC gone mad,I remember saluting my friends even as a child like this,just to be clear its not the full nazi salut just the raising of your arm,I have noticed other races use different methods to acknowledge people,but dont you think its a shame that because of that monster or the PC brigades reaction to him we are now even afraid to act naturally.
