If the 14th, 16th and 17th Amendments were re-presented today for ratification, it would take five minutes for 38 states to ratify.
Maybe so, but it will be because of 4 generations of intentional propaganda in support of them, and no discussion of their true roots. Did anyone in your American history class discuss the nature of the "governments" of the states when the 14th was "ratified"?
Things change. Once the debate is engaged, old assumptions about the outcome will go out the window. The effects of the 14th and other amendments will be seen for what they are: a dystopian America, ruled by the cold abstractions of rigid, ideological judges, unelected, unrepresentative, unaccountable.
BTW, since you appear to be a fervent defender of what The Radicals Have Wrought, you do agree that "it would be a violation of the equal protection of the laws not to allow gay people to marry", right? That's the legal hook that they are hanging their argument on.
Tell me now that a) The Radicals intended for that to be the outcome and that b) the states would re-ratify in a flash.
