So you are saying that human value is founded on how dependant a person is on another person. If you are a teenager, then you are dependant on your parents to provide you with everything. If you are dependant on insulin, pacemaker, and breathe machines, you are dependant on something else to live. Would you allow that person to be killed because they are entirely dependant on someone else?
Forced? What are you talking about? With sex, comes a baby! There is no force or mystery there!
The baby does have an established life. It has a heartbeat, a brain, a separate DNA, 10 toes, ten fingers, different sets of organs, etc. Did you know a baby even sneezes in the mother's womb?
There is no logical or truth based argument that would allow you to kill a baby, financial prosperity is definitely not one.
The saying "My body, my choice," I agree with. The mother should be able to make any choice she wants, as long as it does not violate the life or safety of the other life inside her.
