Sadly, probably not. For the pro-gun, pro-2A group, there's more than a 'sufficient amount of these overly vocal "I have the right!" azzhats out there among us.I wonder if he was a plant from one of the anti-gunner groups. Set him up with a carry license, and a firearm, just to go make an asshat out of himself without breaking any laws. I wouldn't put it past them.
ARE there some on a forum the size of INGO? Probably, just by the sheer volume of the members. If that sounds 'snarky', it's not intended to be, just a factual observation.
For 'snarky', there's likely a selection of those above, pretty easy to spot, for those that choose to bother with 'em.
