The Washington Post recently launched a new Discussion Groups section where readers can join WP staffer and others in talking about politics, culture and other topics. Our friend Ramesh Ponnuru, senior editor for National Review, is the moderator for Right Matters, a section devoted to “Talking About the Future of Conservatism.”

Today’s discussion is on a ruling by Judge Robert Hanson’s ruling that declared Iowa’s marriage laws unconstitutional, and ordered the county recorder in Des Moines to issue marriage licenses to same-sex couples.

Judge Hanson is utterly dismissive of the concerns of opponents of same-sex marriage, which he treats as irrational and illegitimate.

The decision is a gross act of judicial activism. Advocates of same-sex marriage make a serious case: but that case should be made to voters and legislators, not to judges. When the people of Iowa adopted their constitution, they surely did not mean to embrace principles that would lead to same-sex marriage. If they want to do so now, they can; but courts should not pretend that they already have.

If judges can rewrite our most fundamental laws, are we still a self-governing country?

This is a great forum for conservatives to explain our rational and legitimate reasons for opposing same-sex marriage, so drop by and present our case.
