@trz4747@mstdn.social From the laws that ban "assault rifles". California's "assault rifle" ban, for example, allows you to own semiautomatic rifles with detachable magazines. But not if it has a flash suppressor, or a folding stock, or <insert random list of features nobody cares about>.
Literally that: you could have two rifles totally identical except one has a flash suppressor and the other doesn't. That makes it an "assault rifle", in CA, and it becomes illegal.
I assert to you that this is silly nonsense, and has little chance of saving any lives. I think that was @freemo's point.
In other words: "My only point here is "assault rifle" bans, as I've seen them at least, seem pretty stupid."
