Since the US is a christian nation, christian morals should dictate the definition of marriage

Because Pro is making a positive statement he has the burden of proof.His argument right now is this:P1: If the U.S. is a Christian nation, Christian morals should dictate the definition of marriage. P2: The U.S. is a Christian nation.C: Christian morals should dictate the definiton of marriage. I will first attack P2, which is blatantly false, and cause the resolution to fall apart.The United States is NOT nor has it ever been a Christian nation, nor was it found on Christian values. There are only two references to religion in the U.S. Constitution: the First Amendment, which sets up a separation of Church and state and PREVENTS government and church from intermingling, and Article VI, which prevents any religion test for public office. [1]If this were a Christian nation, why did the founding fathers set up the first secular government in history? There are also a few relevant quotes that I'd like to bring up from the founding fathers which debunk this resolution completely.Treaty of Tripilo: "As the Government of the United States of America is not, in any sense, founded on the Christian religion; as it has in itself no character of enmity against the laws, religion, or tranquillity, of Musselmen; and as the said States never have entered into any war or act of hostility against any Mehomitan nation, it is declared by the parties that no pretext arising from religious opinions shall ever produce an interruption of the harmony existing between the two countries." [2]Thomas Jefferson: "Believing with you that religion is a matter which lies solely between Man and his God, that he owes account to none other for his faith or his worship, that the legitimate powers of government reach actions only, and not opinions, I contemplate with sovereign reverence that act of the whole American people which declared that their legislature should 'make no law respecting an establishment of religion, or prohibiting the free exercise thereof,' thus building a wall of separation between Church and State ..." [3]And, well, there's more where that came from. How about the time when James Madison said this would be the best of all possible worlds if religion didn't exist, or when Ben Franklin said that lighthouses were more useful than Churches? Many of the founding fathers were deists. Now that I've refuted P2, the resolution falls and my opponent cannot win this debate. But I'd like to move forward on this though and attack this resolution from a different angle.Even if the United States WERE a Christian nation, marriage would NOT be one-man, one-woman. In fact, Biblical marriage was POLYGAMY. Here are a few relevant verses:Genesis 4:19: And Lamech took unto him two wives [4]Judges 8:30: And Gideon had threescore and ten sons of his body begotten: for he had many wives [5]1 Samuel 1:1-2: Elkanah ... had two wives; the name of the one was Hannah, and the name of the other Peninnah [6]2 Chronicles 11: 21: Rehoboam ... took eighteen wives, and threescore concubines.

He cannot possibly win this debate because he cannot possibly meet his burden of proof.
