But the thing is, the standards of those particular, private organizations don’t rise to the level of a harmful discrimination because they do not remove anyone’s ability or capacity to the free and full exercise of all of their legal rights.
I have freedom of speech. That doesn’t mean that I can say whatever I want, wherever I want. I have freedom of association. That doesn’t mean I can hold a meeting on my neighbor’s lawn or in the middle of the public library. If my neighbor or the library permit my meeting, great. But they’re under no obligation to do so.
I can be married by my pastor, by a judge, a ship captain, a mayor, a justice of the peace or a city clerk. Only the city clerk (and perhaps the justice of the peace) has an obligation to perform my wedding, but there is always that one option available to me, and that wedding is as valid and meaningful insofar as my rights are concerned as any other.
Therefore, I am not harmed because I can’t be married by a Catholic priest, in a Mormon temple or standing under a chuppah with a rabbi. I may be inconvenienced, I may have my feelings hurt, but I can still be married. And that’s as far as my rights go.
There is no right to be married in any particular place, by any particular person or with the ceremonies of any particular faith, ethnicity or tradition. That the option exists for those who conform to the requirements of those places, persons or traditions, expands freedom, it does not restrict it in any way. Removing that option out of spite because it’s not available to all lessens freedom.
You’re not asking for a world free of discrimination, because your “ideal” discriminates against people of faith. You’re asking for a world where your personal brand of discrimination is law, and where people who don’t conform to your beliefs don’t have any stake in society. You stand the notions of both freedom and bigotry right on their ears.
