Like any other law even this one has exceptions! the exceptions you mentioned, Snozz, are legitimate reasons to grant an abortion.
This whole topic is very emotionally charged cause there are so many cases to support both sides of the coin.
And after all it's not up to men's world.
It's the woman who has to decide.
IN my opinion women are very very influencable by scoiety and family. It's like and imperative for them to submit to the laws, not to rebell, not to do "their own" thing. Once her group has decided something is wrong or right, they change their mind in the middle of their argument.
I've seen it that often!
I know a girl who did an abortion - same case: condom exploded

and guess what - she felt ashamed about it and guilty!
In the end she (about half a year later) got a baby on purpose.
There are plenty of methods to prevent to get pregnant for example a temperature measurement which is VERY reliable! Combined with condoms i see the risk of getting involunantarily pregnant go to zero!
Thanks.
