While the gun loonz might enjoy getting their knickers twisted into tight little knots, because it is not the usage THEY prefer, it is in fact perfectly correct usage, and accurate terminology. It is you, the gun loonz who have been getting your words wrong.
How fortunate you have people who fact check your assumptions, so you don't have to do so.
So, get used to it, get over it, and quit whining and making inaccurate corrections to other people using perfectly proper words that are correctly interchangeable.
If you absolutely MUST correct someone, please update your fellow gun lunatics that they are the ones who are incorrect. It will be fun for you, and you will be doing them a favor, preventing them from looking foolish when one of us corrects them instead.
