My point was the unlikelihood.
Yes keep a gun at home,
A firearm at home does you no good when you're being viciously attacked abroad.
but concealed carrying to Church because the one in a trillion chance of something happening?
Ridiculous hyberbole. Just off the top of my head in under a second, there was the two relatively recent Texas and South Carolina "church" massacre shootings. There certainly aren't one trillion churches in the U.S., but even if there were, those two incidents refute your "one in a trillion chance" argument.
If you don't conceal carry, that's your prerogative, but don't try to dissuade other people from exercising their inalienable rights of being armed in a Church.
If a psycho walks into your church and starts shooting people, make sure you tell a concealed carrier, who tries to neutralize the psycho, that you disagree with him conceal carrying in a Church. Maybe he'll pause for a moment to let the psycho massacre you. It sounds like that's what you support.
I mean if you really wanted to be safe, you could also walk around in bullet-proof body armour. Do you?
Bullet proof body armor can't stop a bullet to the head or face from a rife or shotgun slug. What can stop such projectile is using your own firearm to neutralize the aspiring killer before he lays his sights on you and pulls the trigger.
People can still die from internal bleeding after getting hit with a bullet while wearing body armor, even if the bullet doesn't pierce the armor. The blunt force can still cause major internal damage.
