The power of love is that it sees all people.

The marriage institution cannot exist among slaves, and one sixth of the population of democratic America is denied it’s privileges by the law of the land. What is to be thought of a nation boasting of its liberty, boasting of it’s humanity, boasting of its Christianity, boasting of its love of justice and purity, and yet having within its own borders three millions of persons denied by law the right of marriage?

To restrict or legalize abortion, to allow or forbid gay marriage, a legislator would need to write and pass a law, get it signed by the president or a governor, and perhaps override a veto. A Supreme Court justice need only persuade four other people. If he or she is not internally constrained by the authority of a text, he or she is not constrained.
