Property rights aren't natural? What is he smoking?
I'm not usually a fan of John Locke, but his labour mixing theory of natural property rights is perfectly simple (even a DUmmy could understand it) and pretty much sound.
As with DATs appeal to the Constitution you make an appeal to reason.
You will find yourself equally disappointed.
They don't care about those things. All they care about is that you have things they want and they will fabricate whatever argument they need to facilitate their theft. They will disregard law, reason and turn an entire society on its head (i.e. gay "marriage") just to undermine the society built by your laws and reasoning from every angle. They seek to build nothing so much as they work to destroy everything that does not accommodate them.
Consider...
CITIZEN: Oh my God! A bomb just exploded!
PROGLODYTE: It's those RWers! They hate government because they're greedy and cruel to the poor!
CITIZEN: Um, no; it kinda looks like it was leftists.
PROGLODYTE: It's a false flag operation of the RW trying to frame the left because the left stands for the poor!
CITIZEN: Actually, they confessd openly in court.
PROGLODYTE: It's blow back because the RW government oppresses the poor.
Nevermind the fact that the ending defense is exactly what they first accused the RW of committing as a crime. The idea isn't to discuss things logically but to constantly shift so as to keep you off-balance and unable to lay the issue to rest. There mere act of that alone sows as much societal chaos as the bombs. It wears on the civil order and creates confusion, making it increasingly harder for you to defend against their next encroachment. As you run around dousing one fire on the marriage front, they're setting new fires in education or the military or whatever. They count on your efforts to preserve to give them time to run to their next target.
We are unraveling.
They have gain enough followers and sowed enough confusion to destabilize us that they know we are on the verge of collapse. They know they may have as little as 3 and a half years to give us one last nudge.
Why do you think they have become so manic about stripping away the 2nd Amendment? Surely this is not America's first mass shooting in a school. Yet, they have sustained a tempo never seen before.
They know.
Our ideals are no longer a thing we can offer to others out of Grace. They are now the thing we must hold to ourselves as we watch the tempest gather around us. If we endure (I believe we will) we will have our ideals as the blueprint to rebuild...
...until some future generation determines to replay this same farce seen so many time before.
