Linking federal civil unions to guarantees of religious freedom seems a natural way to give the two sides something they would greatly value while heading off a long-term, take-no-prisoners conflict. That should appeal to cooler heads on both sides, and it also ought to appeal to President Obama, who opposes same-sex marriage but has endorsed federal civil unions. A successful template already exists: laws that protect religious conscience in matters pertaining to abortion. These statutes allow Catholic hospitals to refuse to provide abortions, for example. If religious exemptions can be made to work for as vexed a moral issue as abortion, same-sex marriage should be manageable, once reasonable people of good will put their heads together.I'll leave it up to you to decide.
In all sharp moral disagreements, maximalism is the constant temptation. People dig in, positions harden and we tend to convince ourselves that our opponents are not only wrong-headed but also malicious and acting in bad faith. In such conflicts, it can seem not only difficult, but also wrong, to compromise on a core belief.
But clinging to extremes can also be quite dangerous. In the case of gay marriage, a scorched-earth debate, pitting what some regard as nonnegotiable religious freedom against what others regard as a nonnegotiable human right, would do great harm to our civil society. When a reasonable accommodation on a tough issue seems possible, both sides should have the courage to explore it.
But if you're lazy, like me, there's a commentary on the Liberty Papers, which I think is a conservative site but still makes some good points.
