Christian Opposition of Gay Marriage is Silly

I apologize if I was not clear, but I am arguing against Christian opposition that is specifically Christian because it is on religious grounds or out of religious conviction. I was not referring to opposition a Christian may offer that is nonreligious and the type that any person of any religious persuasion may offer.However, since I may not have been clear enough, I will continue normally and answer the arguments of my opponent.Rebuttals of ArgumentsRebuttal 1 "...it will be a lot harder to have kids...": While this may be debatable, it is irrelevant. The difficulty of having children is not a good reason to oppose a marriage, or else Christians should also push for fertility testing of heterosexual couples prior to marriage, as well as evaluations of mental, physical, and financial health, which are all factors that may affect the difficulty level of having children."Who will breast feed the child.": I don't believe breastfeeding is a tenant of Christianity. Unless it is, and Christians who formula feed are treated as sinners in need of repentance, then Christianity as a religion can't use this reasoning to oppose gay marriage. If we reduce it to a personal level, and say a particular Christian opposes gay marriage because they want to rescue innocent babies from their formula feeding parents, this is still inconsistent reasoning. To be consistent, that Christian would have to also oppose marriages between heterosexuals who intended to formula feed, and support gay marriages that intended to use a wet-nurse, obtain breast milk from a friend, or buy breast milk using a service such as this: onlythebreast.com"Girls who are raised apart from their fathers are reportedly at higher risk for early sexual activity and teenage pregnancy...": First, if you are going to use statistics or research, please cite your source. Second, even if this is true, it is not something that should concern a Christian. If the girl in question is not a Christian, then, according to the Bible she is blind and dead, and can't help but sin:2 Corinthians 4: 3-4 - "But if our gospel be hid, it is hid to them that are lost: In whom the god of this world hath blinded the minds of them which believe not..."John 8:44a - "Ye are of your father the devil, and the lusts of your father ye will do..."John 3:19 - "And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil."Psalm 58:3 - "The wicked are estranged from the womb: they go astray as soon as they be born, speaking lies."Ephesians 2:1-3 - "And you He made alive who once walked according to the course of this world, according to the prince of the power of the air, the spirit who now works in the sons of disobedience, among whom also we all once conducted ourselves in the lusts of our flesh, fulfilling the desires of the flesh and of the mind, and were by nature children of wrath, just as the others."If the girl in question is a Christian, then, according to the Bible, God will help her avoid sexual pitfalls:2 Corinthians 5:17 - "Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new."Ephesians 2:1-3 - (Quoted Above)Proverbs 3:5-6 - "Trust in the Lord with all thine heart; and lean not unto thine own understanding. In all thy ways acknowledge him, and he shall direct thy paths."Psalm 23:3 - "He restoreth my soul: he leadeth me in the paths of righteousness for his name's sake."John 8:36 - "Therefore if the Son makes you free, you shall be free indeed."So, as you can see, Christians have no reason to worry about the lesbians' daughter's sex life.Rebuttal 2 Do any Christians oppose gay marriage for this reason? I would be surprised. Obviously, if one did, it would not be a reason founded in his or her religion. However, for the sake of debate, let's say that Christian individuals do use this as a secular excuse for opposing legal gay marriage. They are still being unreasonable. If a gay couple wants to be married, how can you deny them marriage simply because a certain group or a certain gay leader thinks marriage is not in their best interest? Isn't that for the couple to decide? The marriage is not harming them in some physical way that the government needs to protect them from. Even if the 1969 Gay Liberation Front's concerns were valid, the harm being done is to a cause and a subjective value system. Therefore, a Christian supporter of the Gay Liberation Front may believe it is advisable or beneficial that a gay couple not marry, but he or she may not reasonably claim that such a marriage should be illegal. The American government is supposed to protect the liberties of the individual, not the causes of special interest groups.I look forward to reading my opponent's rebuttals of my opening arguments.
