1) The gay-marriage campaign is elitist and believes its opponents are ‘bigots’
2) Same-sex marriage is not a civil right

As to the fourth point, proponents of redefining marriage would go a long way if they could tell the rest of us cretins how we're supposed to tell which of them is the "husband" as opposed to the "wife," if only to pave the way for social etiquette. No sense starting a riot at a dinner party, don't you think?
Or don't you?
UPDATE: Mr Bad Catholic explains why this discussion won't go anywhere anyway. Way to bring the party down, skippy!
