I agree completely. And I also think your point above that was spot on, where you said:
"...if you're dumb/irresponsible enough to carry in a bar while you're drinking, chances are you already don't give a shit what the law is on carrying in a bar. Probably the type of person who is going to jump into their car and attempt to drive home afterward too. I sincerely doubt the law is going change that type of person's decisions."
Sort of goes back to what Rolo and I discussed. Any responsible armed citizen understands the ramifications of a bad decision in connection with carrying your weapon in public. Such a decision could end up with you dead or in prison for the rest of your life. People who care about those kinds of things would never take their gun to a fucking bar where they're going to drink, even if the owner allowed it.
Anti-gun people love to try and scare people by painting this terrifying picture of shootouts in the streets (as Anti said earlier in this thread) or bars (as Rok alluded to). The reality is, shootouts are already happening in the streets in this country. Take a trip to the high crime areas in Oakland, Chicago, Memphis, or any other major city in this country if you don't believe me. Or just do a YouTube search. The gun control laws don't effect criminals, idiots and mentally ill people because those people don't give a fuck about laws.
