It was not a gun massacre at all. Your desperation is showing.
Desperation? I think you have that backwards. I feel just fine standing by the points I've made. I've pointed out that gun technology progressed before, during, and after the 2A, yet they left it broadly open. Again, do you think they thought gun technology was not going to move any more forward?
I've shown that if people want to kill, they don't need high capacity mags and suppressed AR15's to do that. You've ignored it because that doesn't fit your narrative.
You continually hold guns to a standard you hold nothing else to, even if those other things are far easier to get and far deadlier, much higher body counts of both innocents and self-harm.
The anti-gunners are like evangelical religious nuts. You won't look at logic and evidence, you just hold on to what makes you feel good inside and if any thinking goes against that, you can't or won't process it.
If you were really concerned about saving lives, there is much lower hanging fruit to pick. Much bigger killers that are much less regulated, and also tend to affect minorities and the poor more. The ATF is in charge of regulating alcohol, tobacco, and firearms. Of those, which is the biggest killer? Which kills the least? Which is easiest to get and least restricted? Which is most restricted? But it isn't about saving lives, its about your indoctrinated propaganda-lead anti-gun stance.
