Gay marriage: It’s not about liking it. It’s not even about morality. It’s about realizing it’s none of your business.
If two people want to associate in a certain way, and define this association in a certain way, how is this anybody else’s problem?
The state divides a people by requiring all residents of a certain geographic location to submit to its definitions, among the least important of which is ‘marriage.’ This is monopoly, as opposed to people freely associating with churches or other organizations that officiate and sanction what to each of them constitutes marriage. Such freedom is what makes society dynamic, and keeps it responsive to real threats to the social fabric, e.g. violence, and all institutions that rely on it to retain their monopoly.
As it is, the rationale of marriage, that is, ensuring economic assistance to child-bearing and unemployable women, is just about obsolete in this day when a working mother is no longer a big deal.
