"...because the baby depends on the mother to survive, it is ultimately her choice because she is the one who is supporting the baby and taking care of it."
So, you admit it's a baby, but you STILL think a woman should be able to kill it? That's called murder. That's not logical, so your "best approximation of logic" is flawed. And What exactly is an approximation of logic? I know there's an APPLICATION of logic, but I've never heard of the other one.
"Until there is a way to remove the unborn baby from the mother without killing either of them, the choice should rest on the mother..."
There is a way. Carry the baby to term and deliver it. And abortion doesn't kill the mother, so I don't get your logic.
"...influenced by sexism and racism and religion."
Neither sexism nor racism, especially racism, has any bearing on whether abortion is right or wrong. But since you mentioned racism, do you know why Margaret Sanger, a rabid racist, established the forerunner of Planned Non-parenthood? She was a eugenicist. She wanted to reduce the number of black babies being born. Articles have come out stating she wasn't racist against blacks as some people say when they refer to an out-of-context quote from her about "exterminating blacks." But I contend that, even in context, her quote upholds what is thought of her:
“She started “The Negro Project” in 1939, with the aim of expanding birth control services for Black communities in the south, according to the New York University’s project documenting Sanger’s writings." Sanger, regarding how to answer people who might accuse them of trying to reduce the black population, said:
"The minister’s work is also important and he SHOULD BE TRAINED, perhaps by the Federation as to OUR IDEALS and THE GOAL THAT WE HOPE TO REACH. We do not want word to go out that we want to exterminate the Negro population and the minister is the man who can straighten out that idea if it ever occurs to any of their more rebellious members.”
Sanger believed in selective breeding; eugenics. Some think the full quote acquits her of being a racist, but I think the wording is clear and convicts her. She wanted the minister trained in HER ideals and HER goals.
God did command us not to murder but, as I wrote before, even Atheists know that murder is wrong.
