I couldn't read much of the article in this week's Times Magazine about the crusade against gay marriage, because the people who oppose it make me almost too angry to think. But in the few snippets I read, I couldn't help but notice this (on page 2 of the web version):
[Anti-gay activists'] passion comes from their conviction that homosexuality is a sin, is immoral, harms children and spreads disease. Not only that, but they see homosexuality itself as a kind of disease, one that afflicts not only individuals but also society at large and that shares one of the prominent features of a disease: it seeks to spread itself.
Emphasis added. Hey folks - seeks to spread itself? Doesn't that sound a lot more like evangelical Christianity than like homosexuality? Yeah - it did to me, too.
