I haven't presented a slippery slope argument, my argument against legalized gay marriage is based on the precedent of establishment of marriage based on sexual behaviors. Our Constitution prohibits us from denying one group the rights we allow to others, so if we base marriage on sexual preference, we must also allow other sexual preferences the same consideration, if we don't, we have violated their constitutional rights of equal protection. We can't define marriage based on sexual behavior without making sexual behavior a tenable criteria for marriage across the board. You enable the argument for pedophilia, bestiality, necrophilia, polygamy, etc... You set the precedent by allowing marriage to be redefined in law, under the constitution, under the 'equal protection' clause. It's not a slippery slope, it is the principle of law, and how it would have to be applied equally to all. The only thing that would stand in the way, would be striking down some laws currently on the books, but in some cases, no law may apply. I don't know that anyone has a law that a woman can't let her Dobie mount her... is that illegal? Yeah, it's gross, but it's not against the law, as far as I know. So once gay marriage is "approved" by our government, who's to say that the National Women Who Love Dobies, aren't going to lobby government for the same equal consideration under the law? You may argue that animals can't give consent, but I'm sure she could demonstrate how the Dobie consents to mount her, if you needed proof. So who are you to deny true love? Who are you to tell others how to live? Why can't the Women Who Love Dobies have the same "right" as everyone else? Do you have any answer for that? Nope... because according to the Constitution, once you've established marriage can be based on a sexual preference, you MUST grant equal protection under the law.
