Don't forget that some of the posters on this site might be anti-gunners trying to promote firearm hysteria by making it seem like those who are involved with firearms are slack-jawed, drool-spitting morons. I find it hard to believe that anyone would ask either of the two questions that were listed unless it was in an HCI (aka Brady Campaign to Prevent Violence) class.
Good point; we do get our share of trolls (just seem to pop out, raise a ruckus, and then disappear). I have thought the same thing (they're anti-gunners). Welcome to the site, ATX.
