Then perhaps next time don't phrase it in such a condescending way. Anyone who carries a weapon should already understand the gravity of its use. Further before actual carrying they should have discerned whether they have what it takes to use it. The first time you have to shoot someone, shouldn't be the first time you thought about it. Finally your misuse of scripture, no comment should be required, but that is what lefty's do.
Oh get over it. Not everyone who misquotes scripture is a lefty. Bob is no lefty. But the Bible does call us to correct each other not beat each other over the head like lefties.
