"As soon as someone starts talking about banning people of one political persuasion or other, from anything, it starts alarm bells ringing for me."

Much as I detest what the BNP stand for, me too. The dilemma I have is: should members of avowedly racist organisations be allowed the freedom to police black people, teach black kids, look after elderly and infirm black people and so on? Can we trust them to do the job fairly, to the best of their ability and to give their black clients/pupils/patients etc the same quality of service and care they would give their white counterparts? This isn't a theoretical debating point but a real life dilemma that's being acted out around the country right now. Not sure what the answer is though. It may be about capability managing those in that position.
