Just one thing to point out, at least how I see it.
In this case, and in most similar cases on the state level, the government isn't deciding this: the people are through referendum. Based on your description, I would assume that's how Kansas is doing it.
I do agree that marriage should be dropped from the government to be replaced by something else that can be inclusive to all. Simply make it a contract two people can enter into that gives them the same rights that are given to "married" couples, just without the name and, therefore, the connotation.
Good post though. Your grammer needs a little work
, but very well put.
