Not really. You'd still have way too many stupid and hateful people.

I'd gladly take an unarmed stupid, hateful people over this

And yes, I do mean slightly, but am not going to go more into details of the other methodology with much higher body counts that the hatred of small minded folks have taken over the years

Apologist bullshit. There is no reality where this man threatens an Uber driver with a truck bomb. Even when talking about domestic terrorism, bombs are far more effort with far more risk, which is why they're not already used.

They'd just be slightly less dangerous stupid and hateful people.

Which is the point?

I dunno, I reckon they'd be a lot quieter if there's an actual danger of physical harm to themselves.

Guns make people too eager to do crazy shit. You're not going to try to force somebody out of their car with a flick-knife.
