Pakistan currently has a set of laws dealing with the area known as blasphemy. To put it bluntly, you can be executed for saying negative things about religious beliefs. Such laws really are an affront to rational thinking and open debate; to protect such notions with what amounts to state sponsored death threats is truly barbaric. It would be akin to having someone executed for saying they think whale hunting is a good thing; it does not matter if they are right or wrong, they have every right in the world to voice their opinion.
In good news, Pakistan is looking to relax the blasphemy laws a little though the Government denies any plans to remove the death penalty component. That has still angered a few people and it resulted in everyone’s favourite peaceful activity; riots (because everyone knows the best way to get your point across is to go destroy stuff in the street. Great thinking).
