The fool doesn't understand the power of Palin's appeal to "that streak of libertarian." (Disclosure: I am not a member of the Libertarian party, as it has come to mutilate and distort true libertarian principle along the same lines as Romney mutilated and distorted "conservatism.")
Does the Christian who serves Christ advocate for law to seek and punish homosexuals? Does that Christian want to create law that would specify that homosexuals may not pretend to get married, and that they may not become adoptive parents?
OR does the Democrat party, the left, the liberals, progressives, facists, Marxists, Socialists, communists, atheists -- anybody not described as "conservative" -- does that faction of America advocate for law to seek and punish businesses, churches, schools, businesses, and adoption agencies that tell those homosexual to go somewhere else?
What kind of adoption agency would allow the precious childrens' souls entrusted to their care, to be taken up by such declared perversion? Catholic agencies in Masschusettes closed down before doing that. How long would an adoption agency last that did, before public pressure or vice cops closed it down? How well received would a civic organization for boys, such as the Boy Scouts, be if it openly embraced and welcomed people in leadership who declared a preference for homosexuality? Voluntarily, in a free-market social America with no laws specifically prohibiting and prosecuting such living-out of open homosexuality, how long would such pro-homosexual enclaves exist?
When Palin talks about "the libertarian streak" in Americans, I believe that a very large part of that group are Christians and moral, good Americans who just want the goverment, especially the Federal government, to get out of it. They know that limited government is what's needed for people to live morally -- right now, government acts against and seeks to prosecute certain moral choices, such as the one of peacefully discriminating against individuals who declare preference for homosexuality.
Yet there is a virulent strain of resistance to the truth that libertarian limited government principle and Christian morality can indeed coexist (and in fact have fairly well for the first 200 years in America before leftist government came in to enforce their view that it's immoral to peacefully, willfully descriminate against those who openly declare homosexuality).
There are some Christians, who all to often are defaulted to "conservative" status, who also crave government authority to prosecute their own definition of "bad" moral choices -- for America's good, of course! They hate libertarianism with a passion.
