Sharia law isn't even used in the vast majority of Muslim countries in the first place. Inform yourself for pete's sake.
And the whole 'well, you decided to have sex, so you need to endure the unwanted child'' argument is pure nonsense. ''well, we won't save you from injuries resulting from a car accident, you just had to not take your car!''. This is the kind of logic we're dealing with. Unwanted pregnancies happen all the time, and heartbeat means shit since it can easily happen before the woman is even aware of her pregnancy. Furthermore, every period a woman has can easily jettison loads of fertilized eggs off her body. Does it mean every woman who had a period shortly after sex is a serial killer? Come on.
