I agree with you in general. In reality, if we want to be objective the fetus is a form of a parasite. It would do anything to survive, including killing the mother. Since the mother is the sole provider of the fetus' life, only her can decide its fate. Nobody else, for whatever social, cultural or religious reasons.
Invividual rights are above collective rights. The fetus is an individual living at the expense of the host. Even if there is 1% chance of miscarriage, even if the woman doesn't feel carrying the baby because her future will be altered in any way, she can abort it and nobody get to have a saying.
What about the other half of the dna aka the Father?
