But you are wrong. The stand I took that ended my stay in the General Assembly was for an amendment to prohibit the state licensure of mariage altogether.
This amendment to the mariage amendment was voted down 43 to 71, and the only weapon my opponents had to use against me in the 2012 election was my opposition to the Constitutional amendment to define marriage.
I still think I would have won if I had had as much money to spend as they did, but that's neither here nor there. The point being that I stood to denounce 'all marriage licensed by government' when it really, really counted, in what is generally considered a 'career-ending series of votes,' picked up 43 votes in the effort, and when I did so I gave such a heavy 'Christian' argument against state control that I (uncomfortably) felt more like I was delivering a sermon than a House Floor argument.
So what are you using to determine that "Christian libertarians" refuse to be consistent? The tenor of conversations on an internet based discussion board, where you have likely missed half or more of the conversations on the subject, or what actually happens in the State General Assemblies when the laws surrounding this topic come up for debate?
Because it's not the discussion boards that matter, but the legislative bodies, and I'd say that whenever we land in a legislative body that brings this matter up, we do a pretty good job staying consistent.
