You did not answer the question.Laws are not written in stone. Who told you they were?
True. And the "it's the law of the land" argument is kinda stupid for that reason, but it does contain a morsel of truth. Namely, that when you've had two consecutive presidential elections fought on the same topic and the same side of the question won both times, it's properly worth considering that it's the popular will.
The question wasn't addressed to me and I rejected the core argument being made by the person you were replying to.
