From the front of the house to the back of the house and everywhere in between.
Is the person bringing the gun afraid for his life? No. Is he hunting game? No. Is he looking to fend off terrorists? No. Is he going to start a revolution at that moment? No. Is he hunting for quail? No. In short, did the protester bring a gun to the protest with any intention of firing it? Not at all.
He brought the gun for one purpose- to scare and intimidate people who disagree with him. It is an implicit threat that, if health care comes to this country, him and his friends may have to get violent. Or put another way, he’s hoping that by exercising his second amendment rights, he can scare people out of using their first amendment rights. Even if this is legal, can’t we all agree that this is somewhat dickish?
