Its a difficult one Pat, I never cease to be amazed at the levels of racism that exist in this country, but much of it tends to be very subtle and always based on ignorance. As a personal rule, I believe it should always be challenged either personally or professionally, and sometimes you may lose a friend or client and othertimes it may get someone to reassess their position. Most importantly, if they are not challenged then they will be past on to the next generation, and whole families are tainted by this view.
