For god's sake! Some of you people are so keen to see a double standard you talk absolute horsecack.
1) White Policemen Association - I would naturally assume it was a racist organisation since the UK is an overwhemlingly white country and therefore not worthy of mention. Similarly, I would be a bit suspicious of the Black Policeman's Association in Botswana or the Two Legged Policeman's Association anywhere. Even a five year old can understand this sort of logic.
2) Asian Business Guide. Ditto most of the argument above + if you saw a list of businesses that had hearing loops for the deaf, you wouldn't call them 'deafist' or 'hearingist' unless you were a bit simple. Oh, hang on.
3) I wouldn't hesitate to call someone 'the black guy' if that were the simplest way of indicating who I was pointing out. Neither he nor I would consider it racist, unless he were some sort of halfwit. If there was one person wearing a red jumper and everyone else was wearing blue, I'd mention the red jumper without a qualm. Some of you would apparently have palpatations at the mere thought of having to say the word black.
4) Reduced prices based on ethnicity is - gasp, they've done it! It's a miracle - actually a genuine example of discrimination and should have been reported to the police.
