A prediction I have made for years: it will be the right, specifically the national conservatives, who “come for the guns.”
You can see little seeds of it in the shifting discourse after one mass shooter turned out to be trans. Just wait.
It will happen if they gain real broad spectrum power. The deal will be “now that good nationalist hard right wingers now run the police and FBI you don’t need those guns anymore, and we can’t have dangerous degenerates with guns now can we?”
Think I’m nuts? Look at how fast the Trumpists were able to flip the militia / conspiracy subcultures into supporting secret mass arrests and limitless state power as long as “the patriots are in control.” Look at the whole Q narrative and adjacent things. Total 180 degree flip into cheering for the stuff they were paranoid about for decades.
Fascists always lock down power as soon as they have it. They will also ban encryption and cryptocurrency. The Greenwald orbit will act really surprised. Maybe that surprise will be genuine. After totalitarians come to power there’s always a subset of their supporters who are very surprised when they get instantly tossed under the bus.
The left likes to scream and virtue signal about guns but they’re not truly or deeply authoritarian enough to do what it would take to execute on it. (Which is a good thing.) They also tend toward a maximalist interpretation of the rights afforded by the constitution, which makes it hard to argue for a very narrow interpretation of the second amendment without tossing things like gay rights and reproductive rights.
