It's one thing for gay couples to adopt their own lifestyle, but they've moved far beyond that. Now they are demanding that the rest of society change its traditions and institutions to suit them. This isn't about insurance or inheritance benefits for gay couples (which I have no problem with). It's about redefining an institution older than civilization itself. If a two men or two women can marry, why not three men or four women? Or fathers and daughters who happen to be consenting adults?
