It's not really my place as a bloke to say whether women can have abortions or not.
If a woman wants one, and they are fully aware of the risk of an abortion (they aren't 100% safe and can have quite serious side-effects) then it is up to them.
I wouldn't put a law or restriction upon abortions in general or even for certain cases.
The moment you do that, you get people taking back-street abortions, which are usually downright barbaric and dangerous for the mother.
For me, personally, I find the mother to be the most important part of a pregnancy.
It all revolves around them.
The child does not take precedence over the mother.
This is true in normal births. Doctors will always try to save a mother over her baby.
And in the same way, I believe that a mothers health (both mental and physical) should come before any possible children.
