Let me put it this way ... what do you think would happen if this happens 20x more this year ?
You're not doing any gun owners any favors by unnecessarily scaring the sheeple ...
At some point, it normalizes the behavior. I'm not advocating for this, but the rationale behind pushing the limits of what is conventionally accepted is to normalize greater liberty. The homosexual activists have long practiced this to great effect. Two men kissing in a Walmart would have caused an uproar and criminal charges in the not so distant past. Today, people routinely push their carts past such a scene and ignore it as none of their business as well as they can. I have no doubt there are some open carry activists who dream of normalizing OC in the same way. I tend to agree with boom boom however, that this man was more likely delighting in baiting reactionists, and drawing attention to himself rather than any purpose or cause beyond his own self-involvement.
A good indication of how political versus how selfish his motives actually were would be how well prepared his legal defense is. If he's done this without any preparation for the legal consequences and is just hoping an awesome lawyer pops out of thin air like a fairy godmother to advocate for his cause, it's a fairly good indication that he foolishly sought attention rather than shrewdly took the opportunity to advocate his cause.
