Mandatory note that the AR-15 is just "Scary Black Gun" and that gun control efforts would be best served by focusing on features and accessories (and especially, actually fucking enforcing licensing and background checks) that actually increase lethality or mass-shooting potential of a gun.
... but the AR-15 fetishism by gun control opponents is cringe anyway.
I disagree with a number of your points but I’m actually more disappointed you you took all the time to write all that out and didn’t bother to take a second to call out the poor trigger discipline shown in the picture.
Nah, she'll figure it out as soon as she NDs through the ceiling. And really, who hasn't had a desk pop once or twice, right? (Hopefully the /s is obvious.)
Most of the factual points are, well, facts. They exist whether you believe in them or not. I'm curious as to where you think they're incorrect.
One point that I don't cover is that, all other things being equal, using an AR-15 for a claim of self-defense is more likely to result in being convicted of a crime (source) because of the way that the average juror perceives the rifle, rather than due to any particular merits of this gun over that gun.
