Spitzer had a Dr. Jim Garlow, the senior pastor of the Skyline Wesleyan Church in San Diego, on as a guest tonight. Spitzer was basically trying to ask Dr. Garlow "and this affects you how"?
Now, I am paraphrasing here, so please watch the interview for the accurate wording of Spitzer and his guest Dr. Garlow.
The Dr. is quite certain that the Constitution is a document of God, as is the Bible. Chicken/Egg thing there. And it wasn't up to him to judge, it was up to God. But God's will clearly states in the Constitution and in the Bible his intentions with regard to marriage between man and woman. So it's the Bible that does the judging, not him.
And as the Constitution is another of God's instruments, he was certain it was not meant to go against the Bible or God's will.
And so that's how NY's law affects him and every Christian and Religious leader/scholar that vehemently objects to the civil right of same-sex marriage / law. Because the law is against God's will.
Spitzer tried to argue state marriage law vs. church marriage law, but Dr. Garlow would not understand nor agree how one could be separate from the other. Of course Dr. Garlow understood that would be Spitzer's question & reasoning, but he just would not go there, being a man of God and all - he does not accept the idea of separation of Church & State.
Dr. Garlow explains that homosexuals are his friends and are in his church and his church offered programs for their homosexual members - whom all church members love dearly. Spitzer asked what sort of programs and Garlow said the programs that help these homosexuals understand that they weren't born that way, so they could make change in their lives and see through the power of prayer and the Holy Spirit and knowing God that they were born to be heterosexual and put a stop to their wrong thinking and the homosexual thinking and sinning.
Long story short, Dr. Garlow from San Diego cares about the NY law because the Constitution is from God and therefore it could never be used to legalize or condone homosexuality or permit homosexual marriage - a sin which is clearly against the will of God and the Bible.
Anyway, that's one possible answers to the talk-show question "why do you care" about something that doesn't directly affect you.

IMO, we can file that reasoning under "God is against homosexuality so the Constitution is too."
