The irony is that people doing this are really being counter productive. All they are doing is scaring people away from their cause into the oppositions camp. It is one thing to be for gun rights until you are two feet away from someone that is heavily armed in the middle of the crowd, and then you realize you are really just one forgotten pill away from getting your head blown away.
By the way the liberal bias isn't against guns. Their biases are against concealable weapons, and assault weaponry. Both of which are really only used for killing people. You don't hunt game with either, and neither are terribly effective for home defense. Honestly in a world full of psychopaths and morons such as these individuals I am leaning towards laws banning these things being a very necessary evil.
This is just stupid really fucking stupid. The only thing they have accomplished is to look like your common street thugs, and to get local lawmakers to consider passing legislation against the behavior. I don't care how conservative your state is. Being the least bit pragmatic tells you that your economy is going to hurt when people are afraid to come to your state, because you let citizens carry automatic weapons into large crowds of people. Do these people have no shame, or hell any common sense whatsoever.
