This requires unpacking:
If there's a push for a socialist society where the foundations of individual rights and liberties are undermined and everybody is thrown together living collectively off one pot of resources earned by everyone, this is one of the goals they have to go to, same sex marriage, because it has to plow through marriage in order to get to their goal. They want public affirmation, they want access to public funds and resources.
... King also said that former Sen. Rick Santorum (R-Pa.) was right to say that legal same sex marriages would open the door to legal polygamy or bestiality. "Not only is it a radical social idea, it is a purely socialist concept in the final analysis," King said.
You realize that King must have no understanding of the word, or that the word has now become synonymous in Foxland with "anything that scares me." How on earth is allowing 2 percent of people the right to marry the person they love a path to redistribution of wealth or government ownership of the means of production? Marriage is an institution that helps people be independent of the state. If one spouse gets sick, it is his or her spouse's first responsibility to care for him or her. Without the spouse, the government would have to step in. Marriage encourages responsibility, long-term commitment, and leads to better health. All of that too helps people remain independent of the state. In fact every single argument that social conservatives make about marriage for straights - and rightly so - also applies to marriage for gays.
The mindset that lumps this in with some amorphous threat to everything good and American is not rational. It is gripped by paranoia, illogic and prejudice.
