I certainly did not mean to be distasteful in my reference to Rosa Parks
No, but I know many open carry advocates who do. As a friend once pointed out, "there's a difference between a woman fighting oppression and a fat white dude strutting around with a gun."
I also once had an advocate yell, actually yell, at me that he wasn't going to hide in the attic like Helen Keller when the Nazis came.
The problem with the "movement" is that it really does attract folks from the fringe, and there's little way of controlling the more extreme elements. Case in point: JT Ready and his actions at last year's Occupy rallies.
