His right to bray forth his desire to convert the USA from a free country to a tyranny with Democrat morons like himself in charge is protected by the first amendment (which his fellow democrats also want to do away with),
However, there are somewhere between 60 and 100 million gun owners in the USA. If only 5% of them decide to resist his confiscation scheme by force of arms, and frankly a general confiscation as he wants to happen is exactly the time for armed resistance, then if only 5% decide to resist, then that's 3 to 5 million Americans who are going to be looking for Irish Bob and filth like Swallwell to drop the hammer on them.
Perhaps he envisions armed SWAT teams murdering "deplorable" families in predawn raids, and doubtless this will happen. But not everyone is going to cower in fear waiting for the crash of their door breaking down. And not all engagements with the police will be to their advantage, and not all government agents will be going home to their families at night. Lessons learned from Afganistan about self forging projectiles and home made claymores will doubtless be applied, and surely there are a few sufficiently versed in chemistry (and a lot less cautious than I am) who will successfully synthesize things like binary VX and attack enemy strongholds with drones.
People like Irish Bob are stupid, ignorant, and so arrogant in their stupidity and ignorance that they cannot envision anything not going their way. They will be in for a very unpleasant but brief surprise.
Leftist are claiming that they will freeze your assets if you are a gun owner and the you will just turn them in to stop the pain. Plan accordingly.
The interesting thing about the breaking down the door scenario, is that you are likely to be killed no matter what you do, so you might as well take a few of them with you.
That will mean fewer of them for the next person.
