Similarly Rep. Tom Ammiano, who is sadly my representative, is a co-author of this bill. He thinks that carrying a gun is an act of intimidation which he compares to bullying. I'd love to hear Ammiano's response about the transgender woman (Ammiano is a homosexual so presumably he might care more about LGBT issues) in a Maryland McDonalds who was beaten so badly she had a seizure. Perhaps if she was open carrying or if somebody in the restaurant was then the two attackers wouldn't have been so bold as to beat the woman for several minutes.
Like C3 said, it's not a requirement to have a firearm when buying a hamburger, but it certainly helps you survive the experience.
