If your logic is perfect.
Then no one has moral authority to have an abortion.
Certainly not to perform one.
I have never claimed my logic to be perfect.
But if the decision maker has the belief that the fetus has not achieved personhood, then using secular reasoning she is within her rights to make the decision that best serves her belief system. And that decision will weigh on her as much as the decision to give a child to adoption often weighs on the birth mother, or not.
When a fetus achieves personhood is debatable i say viability others say conception. And so it goes.
But as a male i don't believe i have the final say as to whether a woman aborts or not, even if it from my own seed. And i don't believe the government should be directly or indirectly funding this elective surgery in any way shape or form.
