Well, this is a serious debate. We do have a legislature that functions that way. But we also have a judiciary that, when called upon, is empowered to do things contrary to the popular will, if it finds those things in law or Constitution.In Massachusetts, polls at the time of the Supreme Judicial Court's ruling to allow same-sex marriage showed popular sentiment to be against it, roughly 57% against if memory serves. But once the court ruling took effect and the populace had opportunity to watch same-sex marriage in action, within two years popular sentiment reversed: about 60% became in favor of it.
Sometimes the courts' independence in advancing unpopular causes reminds why that branch exists, and is so constituted.
