Opposition to gay marriage: It's about personal discomfort and not the Bible

From a very thoughtful piece in Newsweek:

clipped from www.newsweek.com If the bible doesn't give abundant examples of traditional marriage, then what are the gay-marriage opponents really exercised about? Why would we regard its condemnation of homosexuality with more seriousness than we regard its advice, which is far lengthier, on the best price to pay for a slave? Religious objections to gay marriage are rooted not in the Bible at all, then, but in custom and tradition (and, to talk turkey for a minute, a personal discomfort with gay sex that transcends theological argument).
