Legitimise the prostitute, ban the professional blood donor. Yes, strange that just months after the recent, much-hyped Calcutta conference on legalising prostitution comes the Supreme Court-imposed ban on professional blood donors effective from January 1. Discard politically correct nuances in the debate, dump the prejudices, get to the bare basics. And let the harsh irony hit you hard between the eyes. One sells body and one sells blood. Both are poor. Both exercise that cruel mirage called Choice. Both open themselves to grave diseases. Both endanger those who buy body or blood off them. And yet, ponderous editorials support the legitimacy of one while the other is banned. Which, in fact, is bad, which worse?
