I will defend a women's right to terminate a preganancy to my dying breath. The minute you start having to justify the reason, is the minute you start to take that right away.
Having said all that, there is no question in my mind that this is one of the most momentous and difficult issues a woman might have to face. AND some women most definitely do it for trivial reasons: the foetus is the wrong sex, convenience, etc. Some women have children for very trivial reasons.
Still, I see no better solution than to leave the decision up to the woman.
