Man, I had this same exact argument the last time this popped up. According to the Bible, there is no such thing as rape within the marriage bed, so it isn't classified as adultery. But personally, I think that forced sex is possible within a marriage, but that it shouldn't be legally classified as rape. I think that in that case, spousal rape should be used as a point of merit for divorce. Prosecuting someone for rape in addition to the regular divorce proceedings seems superfluous, and if a person stays married to someone who rapes them, then they're just stupid. And I don't think we should make laws designed around the idiocies of the stupid.
