I agree. Adjust and adapt to the newer times and circumstances.
My problem with the "liberal" side isn't even so much in their position - in and of itself. It's the lack of willingness to call it what it actually is. If they support what amounts to an open border, then have the courage to call it that and defend your position on it's own merits. It's this mealy mouthed stuff that irks me. Convince me why having an open border might be a good idea.
And along with the idea of "it isn't 1900 any more", I agree. Maybe birthright citizenship needs to go away, too. Back in those days it made sense - because of the tom-foolery people were engaging in when it came to handle the citizenship of ex slaves. Granting birthright citizenship made sense at that point to put an end to that debate.
But nowadays - it doesn't make the same kind of sense. Join the majority of the rest of the modern world - where citizenship follows that of the parents. That would be an adjustment to modern times that I could get on board with.
