Secular reasons for and against legalising abortion

[Clueless Morgan]

Obj 2. A woman’s right to have control over her own body should also include taking the necessary measures to prevent unwanted pregnancies by the responsible use of contraception or, if contraceptive methods are not available, abstinence.

this assumes that the woman seeking the abortion wasn't taking the necessary measures to prevent unplanned pregancies. No method of birth control is 100% effective and even the best laid plans can go wrong (see what I did there? ). Even if I took every precaution to reduce my chances of becoming pregnant short of abstinence or celibacy, no one has the right to take away from me the ability to make choices about what happens to my body if I become pregnant if I don't want to remain so. Only I get to make that choice, and the only person for whom I can make that choice is myself. I don't get to choose what others do to their bodies just like they don't get to make that choice for me.

With regards to abstinence, that's simply unrealistic. Humans are incredibly social and one aspect of our sociality is our sexuality. We don't just have sex to produce offspring, we do it to increase pair bonding and intimacy and to feel connected to each other. Wide spread abstinence is a moronic thing to expect.
