You do realize that a woman's right to choose, in most cases of abortion, were when she took off her clothes and had sex. Let's not talk about the exception (rape) yet, because that is a red herring and a dodge of the real issue. YOU say, you want a woman to have the right to control her body, and I am 100% in favor of a woman controlling her body. I only wish she would. Because what we are talking about here, is a woman NOT controlling her body and then expecting to kill another being while calling it "choice".
The next bit, is touchy because it requires logic that most "choice" people don't use, because it is painful to realize you've killed a human. This bit is called "dehumanization", which is what the "choice" advocates call the living being inside. They use terms like "fetus", "fetal tissue", "blob". Once you dehumanize someone, you're no better than those that dehumanize Jews (pigs), Blacks (monkeys) and so on. Then you make them your enemy (loss of freedom) and then you can kill them without conscience.
Lastly, as a Libertarian that has this argument with other (pro abortion) libertarians, my biggest point is, the REAL role of government is to protect the rights of those that cannot protect themselves. The purpose of strength is not to abuse the weak, but to use it for protecting the weak from those that would use their abilities to harm others. IF we, as a people, stop protecting those that have no ability to protect themselves, we have lessened ourselves as humans. I will always side on the defense of the defenseless unborn child, because that is what defines me as a human.
Those that use "choice" to kill the unborn, have defined already that they are willing to kill for convenience (birth control). And that is inhuman.
