Ummm. it starts as an outlier discussion then it moves toward the mainstream.
More than one senator has already expressed that desire and it will only really take a switchover in Congress to legislate an outright ban and when that doesn’t work, confiscation isn’t far behind.
I expect to see the govt do something with background checks that makes it impossible to get a gun at a show and they will restrict the import of ammo, guns and mags.
I expect that at every corner like when you need to renew your license, registration, or special endorsement for a CDL, there will be a checkmark if they have a red flag about that registered gun you bought 20 years prior, and until you can prove its long gone you will have to fight tooth and nail to get your credential.
And at the same time they will demand you take a mental health assessment. They know that there will be blood on the streets, so they will take the long term approach, we all need something, they will find that something and hold it hostage.
They will boil the frog, believe me.
