I can’t remember whether I read this from someone else or came up with it on my own, but when people ask “do you oppose homosexual marriage” in questionnaires to find out political orientations, people answering “yes” will include both those who oppose homosexual marriage but are OK with heterosexual marriage, and those who oppose all marriage, and those groups are very different clusters in political space (paleo-conservatives the former, radical anarchists the latter). (Of course, the latter group is so much smaller than the former than if you’re doing statistics with large numbers of people this shouldn’t be such an issue.)
