Pakitstan's Blasphemy Laws Abused

Pakistan has some strict blasphemy laws, which can be taken advantage of if you're mad at a non-Muslim.  A Christian woman has been sentenced to death for blasphemy, because she dared to defend her beliefs when she was taunted by Muslims.  Now, first of all, I believe in freedom of speech, so the whole concept of blasphemy sounds wrong to me.  Secondly, if you're going to have a blasphemy law, couldn't you at least use it against people who were actually blaspheming, instead of innocent people who just aren't Muslim?  This issue appears to be dividing the country, with those who support changing the law being attacked for it.  It's pretty sad if you can't even discuss the issue because you're worried about being killed.
