Why don't pro-choice people like to be called "pro-abortion" people?

Pro choice is not pro abortion. The vast majority of those who are pro choice believe as they do simply because they realize the fact that they have no right forcing their opinions and beliefs on another individuals. In fact I would risk saying that the majority of those who are pro choice see abortion as a last resort, one which should be called upon sparingly. However as long as there are those who want to force their religious and moral judgments on others simply because they feel they are morally superior, there will be those who vocally stand up to their hypocrisy and defend the rights of the individual.
