As I said: “First use against nutters is just to make the idea seem socially acceptable.”
As far as I can remember, nobody has ever been all that accepting of people with very public loose screws running around armed. That’s not a hill a person would wanna die on.
Second amendment supporters will be among the biggest cheerleaders of the red flagging of those they consider nutters, losing their rights. Just because they vote Republican and like to shoot, does not make them patriots.
