Civil disobedience can be an admirable and fantastic thing.
That said, most of the idiots on the internet who encourage defiance of unconstitutional law have little to no understanding of the point of undertaking such activities in the first place.
If you opt to flaunt a law you find reprehensible, you had damned well be ready to face the consequences, which could include physical violence, arrest, prosecution, legal sanction and jail time. On top of that, you need to be in a position where your arrest is both in the public eye and likely to result in the average person believing that you're aggrieved to such an extent that they come to believe that the law needs to be changed.
If you look at examples of civil disobedience, those who chose to undertake them were uniformly willing to step up and publicly state why they believed the laws were unreasonable, and they were willing to break the laws in plain view in order to provoke the state into an overreaction, thereby making their point.
If all of the above sounds like a fine past time to you, and you've exhausted other avenues to get the law changed via more traditional methods, by all means, proceed.
But if you carry a handgun without a permit, in violation of the laws, you're not doing any of these things. All you're doing is surreptitiously breaking the law. Deluding yourself into believing that you're taking some kind of moral stand by doing so is plainly idiotic, and does nothing to further the cause of the RKBA. In fact, if you ever get busted, you're going to hurt the movement far more than help it.
