Not once in this thread have you posited an argument as to why gay marriage should be banned by the command of government.
Instead you propose hypothetical scenario's that haven't been a part of the argument because you'd rather argue talking points. Incest and Polygamy have nothing to do with gay marriage. If you want to argue about those start a thread about them.
Wrong, You and your ilk have claimed several things. One is that what two consenting adults do in the privacy of their home is not the Governments business and that equality means that any two consenting adults should be free to marry one another. Those are the arguments used to justify Gay marriage.
So under those standards how do you support preventing two adults that happen to be siblings or parent and child from marrying? How do you, under those standards propose laws that make incest between consenting adults in the privacy of their home illegal?
Okay RGS let me try to break it down for you. Between 2 random gay or lesbian people in this country, there are ZERO laws connecting them together or tying them together in ANY WAY WHATSOEVER.
A parent and a child, or two siblings, ARE BOUND TOGETHER BY LAW BY THEIR ENTIRE RELATIONSHIP.
Therefore you are trying to use a COMPLETELY DIFFERENT legal relationship to justify government intervention into something that you don't like.
