@cicerone imposter,
How fortunate for you that it's an easy decision.
We've probably been down this road before, but if I believe there is a third person involved whose rights are not being considered, let alone protected, and for whom it literally is a matter of life and death, the moral dilemma I'm faced with is quite different from the one your belief system has created for you.
I don't need to rely on religious beliefs to come to the decision that the abortion should not be permitted, anymore then you need them to come to a decision that murder should not be permitted.
I need to believe that human life begins before delivery, and I don't need to have any religious beliefs to arrive at that conclusion.

An argument can be made that I've imposed my philosophical, moral and/or legal beliefs on someone, but how is that any different from your decision that murder is not permissible?
My decision doesn't require that I know anything about the mother or care one whit about her, but the same can be said as regards your decision and the murder.
Likewise I personally owe the mother
