If all this was on our new identity cards...what fun. We could wear special clothes depending on our clan. Or our religion. Or blood group. Or whether we had AIDS or not. Actually, simpler than special clothes, we could just go for armbands. Different colours for, say, Catholics or Moslems or Jews. That might not be enough for some groups though. They may take their armbands off. If you were a paedophile you might get painted yellow. Bankrupts might be painted red - head to foot; just to let everyone know.
We might need to set up special camps for these people to let them - what's the word - concentrate. We wouldn't want the un-British
So bring them on, these new identity cards.
We will probably be able to collect them at special government agencies. They will "give" you a card. In return, you hand over your freedom.
