I fear that you are correct...though I hope and pray that the People never forget the reason why the 2nd Amendment was proposed and ratified (by a bunch of former revolutionaries, FYI).
Nancy Pelosie last week proposed that the first amendment be ammended and of course they have actually just ignored the 2nd for years. When I was born, no one not even the police questioned my right to carry a firearm in my car, they really weren't all that comfortable with slapped on the hip firearms but I never got stopped toting a shotgun or rifle.
Younger people will have to take up that argument, I am done, if I don't die soon of natural causes, I imagine the pain pill treatment plan that Zero plans to offer will speed my departure. It will become law, no doubt in my mind.
