When did it become unconstitutional to exclude homosexual couples from marriage? 1791? 1868, when the 14th Amendment was adopted?
Antonin Scalia[T]he enshrinement of constitutional rights necessarily takes certain policy choices off the table.... Undoubtedly some think that the Second Amendment is outmoded in a society where our standing army is the pride of our Nation, where well-trained police forces provide personal security, and where gun violence is a serious problem. That is perhaps debatable, but what is not debatable is that it is not the role of this Court to pronounce the Second Amendment extinct.
Antonin ScaliaNowhere else in the Constitution does a "right" attributed to "the people" refer to anything other than an individual right. What is more, in all six other provisions of the Constitution that mention "the people," the term unambiguously refers to all members of the political community, not an unspecified subset... The Second Amendment extends, prima facie, to all instruments that constitute bearable arms... The very text of the Second Amendment implicitly recognizes the pre-existence of the right and declares only that it "shall not be infringed."
