Amnesty International is using the NI issue to promote its pro abortion agenda which was initiated over ten years ago and which openly violates the founding member's original aim.

I agree that the concerns raised in the article are valid - there is a huge negative aspect to freely available abortion such as the discrimination of nearly a million girl babies being aborted each year in India, the one-child abortion policy in China and the resulting skewed population that means there are nearly 70 million more men than women in the world's two largest countries, and the associated problems in the economy as well as problems in society due to male loneliness, male violence, sex trafficking, prostitution.
On the other hand, forcing a woman to continue with a pregnancy that she does not want sounds discriminatory, given a man is not in a similar position - it seems like violence against a woman since pregnancy is a physical issue that causes various physical hardships and complications. Having been through it twice I really disliked the vulnerability of being pregnant. So decriminalising abortion seems a valid response to what can be for some, the burden of pregnancy. More importantly than this discriminatory angle, over-populating the planet with lots of unwanted babies seems a crazy idea. For the sake of the rest of the planet, I'd say the less sanctity of human life (and not just for babies), the better - up to a point.
