Pro-Choice Problems

What does PRO-CHOICE really mean? If it means that one has the right to make a choice then I would say I am pro-choice, but I am NOT pro-abortion. I do not agree with abortion necessarily but I couldn't tell someone that they do not have a choice. This conjures a more generalized task of exposing the discrepancies between pro-choice and pro-abortion. Most of those who would jump to debate stand in a rather shallow puddle of preference when it comes to abortion; its either one or the other, period. I like to think that the "moral quarrel" on abortion and the concept of the right of choice should first be separated. As Americans are we not entitled to choose? Isn't that what our government is stationed upon...freedom? What are pro-lifers' pushing for? Denial of abortion or denial of choice?
