Ya, they do. The Las Vegas shooter for example
He had issues beforehand. I don't think he just snapped.
But it is collectivist to ban AR 15s for 20 million people because one of them decided to do a mass shooting.
One? You are not being honest
It might be 100. If there are 20,000,000 AR 15 owners in the US and 100 of them commit a mass shooting, then it's collectivist to take AR 15s away from the 19,999,900 AR 15 owners that didn't murder.
Don’t be a moron. Think like an adult.
It turns out enough actual adults agree with legalizing AR 15s for me to think like a libertarian adult. I believe in freedom if you aren't harming anyone else significantly and are old enough (and the vast majority of AR 15 owners don't), you believe in reducing unwanted pain even if it means you are going to have to institute some level of collectivism. Our morality is different, and I respect yours and I hope you respect mine. We are both anti Trump, for instance; I don't think he is pro LUSHOOTY and you don't think he's AUP.
Weapons of war weren’t always cable of mass murder. Now they are.
Also, a man is capable of beating his wife up. As long as he doesn't do that, he can look like John Cena and have all that destructive power and it's fine. The vast majority of AR 15 owners aren't going to murder (just like the vast majority of Muslims aren't going to be terrorists). Just have freedom! The counterargument you might make:
Muslims are people, guns are not
Muslims and AR 15 owners are both people. Owning an AR 15 and being muslim are choices. Should someone be banned from making a choice because a small portion of people in their group use that choice to do something bad? No. I apply this for Muslims and AR 15 owners; the left pities Muslims for being brown and view AR 15 owners are strong and scary, so they operate on their feelings.
The Founders expected us to adapt to that reality.
On one hand, you say this. On the other hand, you trash the founding fathers for owning slaves.
That’s why they made the Constitution amendable
That doesn't mean it should be amended.
