Nice straw man, but that has nothing to do with your position that fedgov has power regarding the institution of marriage. You seem to be of the belief that fedov has the power to define, regulate and otherwise sanction marriage even though nothing in the Constitution grants it that power.
Oooh. A lib twofer.
I add in arguments that support my position, and you call them staw man. Then you hide behind the Constitution as you continue to rant on against traditional marriage.
Tell me. What is it that has caused your bitterness and anger against marriage? Been through a couple bitter divorces, huh?
