I wasn't suggesting 'you'.I'm not a "gunner" (never owned one), but this isn't a gun issue. It's a mental health and shitty parenting issue. He might have chosen to drive his car into a crowd instead. Would you start screaming for vehicle regulation in that case?
There are two others who are totally obsessed with guns and promoting the 2a agenda. I find it quite curious that anybody would suggest that guns can't be left lying around all over the house.
