It was most certainly NOT envisioned by the framers of the 14th amendment. Neither was "Anchor Babies" and Authorizing non natural citizen Presidents, or kicking religion out of public schools and government buildings/ceremonies.
But this is what happens when you write a bunch of sentimental crap with no clearly defined limits or boundaries, and then force it down people's throats at the point of a gun.
The courts are free to interpret ambiguity and the removal of restraints on their power in any manner they so wish.
The Framers of the 14th were idiots compared to the founders. They tried to do too much and they didn't work hard enough to get the meaning and intent right.
It is a gobbledygook soup, with predictable bad consequences. It is also a consequence of the civil war empowerment of the radical Republicans who were the "liberals" of their day.
I think if you read the original Constitution of the United States or the Bill or Rights, you'll find plenty of provisions that have "no clearly defined limits or boundaries." For example, the 14th Amendment's "due process of law" duplicated the 5th Amendment's "due process of law." And, what famous decisions interpreted "due process of law" in a rather extravagant way to help find a supposed "right of privacy" therein? Constitutions commonly use broad, somewhat vague terms for various obvious reasons. It's really not fair to hold drafters responsible for crazy interpretations
But, I want you to notice that you seem to prefer to blame the 14th Amendment (from the 1860's) rather than the misuse of that amendment in the 21st century. Do you think it possible that you do that because of your strong feelings about Lincoln and because you think that the 14th Amendment is easier to associate with Lincoln than a 21st century misinterpretation of the amendment?
Look at that stretch you're making, all because you have been wanting to blame Lincoln for homosexual marriage. As I've said before, that connection is very dubious. (In fact, you really cannot even properly blame Lincoln for the 14th Amendment.)
But you keep swinging at those bad pitches! :-)
