re: I disagree
Ethics and morality cannot be supported by reason, which is why we have the law. Law can be subjected to reason, although sometimes "reasonable" legal decisions are not particularly just, or even moral/ethical. The fact that we feel it is necessary to put up with that in the interest of justice is evidence that matters of principle are not always amenable to logic.
As for politics, I've been telling you for years that has nothing to do with reason. It has to do with what's right.
