I know there are pro-second amendment DUmmies, maybe this is one and he/she is being sarcastic?
There are some, but of the ones on DU, there are also some of them who are moles from arf.com and guns.net 9f course some of the moles adopt rabidly anti-gun personae, too, just to spin up the DUmmies).
Either way, they enjoy screwing with the primitives, as any right-thinking person does.
