My wife and I settle our arguments by deciding whom an adverse outcome would bother more. Better that one of us be slightly annoyed than the other be greatly annoyed. Rather than cajole each other or come to shouts, we weigh our would-be grievances. This leads to a policy of laissez-faire: if she wishes to attend a reunion and I do not, she goes alone, though she would rather I went with her and I would rather she stay home with me. Dragging me along would bring her less pleasure than me annoyance; vice versa if I stood in her way.
I apply this principle to the issue of gay rights. Discrimination hurts gays more than equality for gays hurts their opponents. At stake for gay people are their own lives; at stake for their opponents, merely others' lives. The effect on gays is material, direct, and daily; the effect on their opponents, abstract, remote, and occasional, concerning only the conformity of society to their moral beliefs. My neighbor, not me, gets to choose how to decorate his living room because he lives in it while I merely glimpse it through his window. Our rights extend only to the property line of our own life.
Traditional values are unjustly said to be under attack by the gay rights movement. An attack entails crossing the border into another's territory. Therefore no one can be an attacker who is merely defending his right to a share of the common happiness available to mortals. Gay rights is an issue of self-defense, which only looks like an attack because traditional values have so long forced a portion of humanity to suffer in silence.
