The "Guns at the RNC" petition was started by... a Clinton supporter. I'll wait while you pick your mouth up off the floor.
The thing is, I wouldn't mind at all allowing permit holders to carry at the convention or most anywhere else. This was intended as a "satire" aimed at making us look like hypocrites, but really, there's no hypocrisy to be had on this issue.
That's how I knew this was a false-flag -- it's the kind of petition someone would write who fell for the "NRA bans guns" hoax. There are only two reasons guns aren't going to be at the RNC, and neither of them is amenable to a petition. The first one is the Secret Service, and the second one is the insurance concerns of the property owner.
