I think you are being obtuse. You really believe that the Founding Fathers were gay rights activists?
What does that have to do with anything? The Const. is clear whether its gay ‘rights’ marriage or goldfish sales. If the Constitution doesn’t cover the topic, it’s up to the staes to legislate or not at their discretion. Period. End of. Done. Does the Const. say differently?
No.
Thats the why it is. There is nothing to argue or be obtuse about. Your dislike of Cruz does not change the wording, nor ammend the Constitution on the matter. It says clearly what it says.
