"A "common law system" is a legal system that gives great precedential weight to common law, on the principle that it is unfair to treat similar facts differently on different occasions. The body of precedent is called "common law" and it binds future decisions. In cases where the parties disagree on what the law is, an idealized common law court looks to past precedential decisions of relevant courts. If a similar dispute has been resolved in the past, the court is bound to follow the reasoning used in the prior decision (this principle is known as stare decisis)."

You see, people like me who are proponents of gay marriage point to the case of Loving vs Virginia where it was ruled that laws forbidding interracial marriages are unconstitutional. Based on common law this can be used in courts to prove that it is also therefore illegal to prevent same-sex marriage. Of course, when I debate with the conservatives about this they say "That's a totally different issue." Not only is that rebuttal a complete cop-out to dodge what is a blatant contradiction in their ideologies, it is also not in line with the American legal system which uses common law to judge cases. Therefore, looking at hypothetical or actual cases that are similar to abortion, i.e., any cases involving the termination of fetuses or crimes involving conjoined siamese twins, are completely in line with the American legal system and can help determine whether it is actually legally for a woman to terminate her fetus even if it is inside of her body and cannot live without the support of her body.
But I don't expect you to understand any of that and its obvious you have no real interest in debating this topic. You've made it quite apparent that there is no real argument from the pro-choice side of things and that the liberals have become extremely closed minded on this issue and are unable to analytically look at any of the complex moral and legal issues involving these laws. Instead its simply "its the woman's choice, end of debate". You guys eerily remind me of the conservatives I debate with about gay marriage who simply say "Its wrong because the Bible says so, end of debate." This is precisely why I'm a centrist.
