Lies. Multiple, willful misstatements of other people's positions. Positions that have been clarified and set for your understanding.
To start with one, every time you say I "support" gay marriage you're willfully misleading anyone who isn't familiar with my actual position, giving them an impression that is at odds with my repeated, qualified statements on both the moral and legal question.
I'm not in favor of gay marriage. I don't attempt to advance that use of the institution. I have, in fact, been clear in my opinion that such a union would be and is contrary to my religious and moral beliefs, exists as a sinful state in opposition to the ordinances of God and the well being of the individuals involved.
I've also stated that my moral beliefs, absent a compelling parallel and secular argument, which I've yet to hear or contrive, cannot stand in the way of the fundamental legal principle in play here, one that is effortlessly exercised by all sorts of people whose unions fall outside of my and your moral wheelhouses. So the Hindu, the atheist, the homosexual, none of whom enter into a relationship before God within the Biblical understanding, are free to enter into a covenant before and sanctioned by the state.
