To repeat a QOTD from a few posts down:
Democrats are using guns to kill each other – and want it to stop – whereas Republicans are using guns to defend against Democrats.Which is why I don't think an assault on NRA headquarters would get very far. Unless the professor could raise a large enough army of pacifists like himself with polished skills at using EBRs.
Most gun violence would end if only we could prohibit Democrats from owning or possessing firearms.
In semi-related news, a man in Minnesota was shot 5 times and killed while reaching for his ID as ordered when he politely informed the officer that he had a CCW and was carrying. Moral: Don't ask, don't tell.
