... and this concludes my TED talk on why everyone in the United States should be armed.
Seriously, though; road rage, drive through rage, having-a-bad-day rage. Background checks are not going to prevent people from behaving emotionally and irrationally.
And what's the 2A advocate argument here? That the driver should have pulled out his own firearm and had a shoot-out with this server, with his wife in the passenger seat and daughter in the back?
"An armed society is a polite society" is the the biggest bullshit.
I'll say it again: I own several guns myself, and I love to shoot. But if the laws changed and I had to relinquish them; and if there was a reasonable chance that it'd actually dramatically reduce the number of Americans with guns, I'd support it. I could live with renting at the range.
