Name a few... rational ones.
#1 Personal choice. Freedom to choose.
#2 Added layer of safety. Some people like a light trigger, maybe others want a stronger trigger for an added layer. Maybe others opt to buy their striker fired with the optional thumb safety for another layer of safety. Stronger triggers and thumb safeties don't generally begat a barrage of accusations of terror or fear of weapons. Why so with C3?
I think you refuse or are incapable of seeing that someone may just want another layer of safety which has nothing whatsoever to do with their fear of the weapon.
If you're arguing that they're not free to do whatever they want within the laws about their CCW then I have a problem with your rationale, not whether or not someone is just making a decision based on whatever they want to base their decision on.
Here's another thought. Responsible gun owners all agree that you should never point a weapon at anything you don't intend to shoot and that under no circumstances would it be appropriate to wave a loaded gun waving around and pointing at people. Why is that? It's impossible for that weapon to fire unless you pull the trigger. With that in mind, as long as you keep pressure off the trigger it's safe. So what is the purpose of not pointing at people?
Maybe I should add one more condition to my "if you can't.......then you shouldn't carry a gun.
Here goes.
If you can't have confidence that you can wave your loaded gun around in front of your family and friends without pulling the trigger then you shouldn't be carrying.
Ridiculous right? It's just a layer of safety though.
They don't need anyone telling them their thoughts and whether or not they are afraid.
Your gun, your CCW, your decision.
