Guns make people feel safe.
They don't actually make you safer.
You're more likely to be killed by your own gun than someone else's.
Realistically, you have no hope of protecting yourself with a gun if you're surrounded by gangbangers with a bunch of guns all pointed at you.
Etc, etc...
The gun debate isn't a debate about facts, it never was. It's a debate about feelings, and scared people won't change their minds unless they stop being scared.
Nobody in America right now is trying to make people feel safe, not in an era where the President of the United States feels it is appropriate to personally attack... anyone for any perceived slight, in public, with verbal violence and in the case of anyone looking even vaguely hispanic, physical violence.
