No, my friend, you are absolutely wrong. Government can make laws that declare marriage whatever it wants, but marriage is defined by two people pledging their lives together before God. The government can scream they are illegal, it can jail them and kill them and you can post slander against them and it means absolutely nothing at all - zero.
Because marriage is made by GOD ALONE. And that is BEYOND government - and the US Constitution acknowledges that relationship.
YOU are the one who is seeing the statist, collectivist command, control and authority of the government over marriage. YOU are the one who would shred the 1st Amendment and have all religions cleared and approved by the government to be "legal." YOURS is the dream of the globalists, the corporatists and the homosexual activists who would change laws as they please and then - as is happening right now - declare religious observance "illegal."
How can you take that position when Christians are being sued, broken and threatened with jail RIGHT NOW in American BECAUSE their religious beliefs HAVE BEEN DECLARED ILLEGAL? Are you blind?!
And yet you demand marriage be subject to declarations of legality? You invoke satanism, polygamy, and Muslims, but that's not what's happening here - CHRISTIANS are being declared illegal FOR PRACTICING THEIR FAITH. So what happens when their "legal" Christian marriage is declared illegal? WHAT THEN?
Study natural law and negative rights - HARD. Until you UNDERSTAND them.
"Law defines what legal marriage is, Islam doesn't, gay churches don’t, satanic cults don’t, individuals don’t, that is why Muslims can’t legally have polygamous marriages here for example, and why gay churches couldn't perform legal marriages until recently."
Islamic polygamy marriage is currently illegal in America, as are plenty of various "religious" and cult definitions of marriage, and you want to make them all available, and in effect, end any definition of marriage in America.
Christian marriage is not illegal in America, but some religion's marriages are. Why do you want them all to become accepted?
Why are you playing this fantasy game anyway, is this your approach to destroying marriage by ending our conservative fight to protect it? That is a common trick of libertarians, to divert the conversation from our political marriage fight, to some fantasies of suddenly completely erase marriage law entirely, which isn't anywhere in the universe of reality, or even desirability.
You are a libertarian aren't you.
So all this bizarre and contradictory talk of God and religion is your way of getting us off of the conservative battle to preserve marriage, and in fact is a fight against protecting normal marriage and conservatism.
