I think your use of the word Idiot, is not what you wanted to portray in your comments. I'd find a word that might be better. An idiot, although not smart enough to have a high paying job, just might be a normal enough person to know right from wrong and live in a manner suited to someone that believes that way.
Yes, being an idiot will not likely prevent one from purchasing a gun.
