No, I am not challenging anyone that says they have been to one that allows loaded guns. I never said they hadn't been to one that allows loaded guns, I said most don't, and people continually keep arguing for some reason, seems some keep imagining that I have said "all". I keep saying most don't, because, well, most don't.
As for the meme-- it's pretty simple too, because its premise and implication is false-- it pretends that terrorists don't attack gun shows because so many people there are allegedly armed-- at most, they are not armed, other than the police there.
Pretty simple ideas, but people seem to be trolling hard tonight and knee-jerking.
