Well, much as I enjoy this debate, I don't think I'm going to argue with you if you think that a perfectly fair analogy is crazy without providing any rational reason. You don't have to like it, but both were/are legal, and yet some people saw/see such as acceptable while others saw/see such as unacceptable. Nothing crazy about that. But I think I'm done defending definitions since I feel like I am continually taken out of context (not just by you, mind you).
Sorry if I'm coming off as snotty. Not my intention.
EDIT: As for the Bible, I'm not sure if you mean in reference to abortions or just using the term at all. Frankly, I'm not sure...but searching on the BibleGateway, it appears that the term murderer is used a few times in the KJV, but not just plain murder. As for the NIV, it gets a bit more usage as both murderer and murder.
Now doing a little research and wasting valuable study time yields some interesting biblical arguments regarding abortion. One site gave some extremely bizarre and stretched interpretations justifying abortion from the Bible. Only a few citations could be considered truly worthy of further examination and rebuttal. However, several other citations support the notion of preserving life. I'd be interested in discussing that topic further, but I can't get on this site anymore today--too much to do.
