...Gee, can't find that part about registering my guns in the Constitution...
You are part of the Militia of Last Resort of the United States - the People themselves.
Registering your guns would merely be an example of Regulating that Militia, Well... as found in the text of the Second.
...Let's register backpacks.
No problem.
The very minute you prove that 30,000+ people die from Backpacks annually, nationwide.
There are gun shows all over this nation frequently, and I've never heard of a gun jumping up and killing anyone. Guns aren't the problem. When are we going to register knives? Knives are killing more people than guns.
Knives Killed Five Times As Many People As Rifles Last Year
You don't seem to understand.
The country at-large has reached a Tipping Point with respect to the status quo.
You are going to see more and more evidence of this over the course of the next election or two.
Wordplay and simplistic bumper-sticker -caliber pro-Gun slogans are not going to prove to be an adequate defense for what's coming.
Believe it.
Adapt.
Or suffer the consequences.
You have been warned.
And you're running out of time.
