I think the key to this is as long as the permit holder follows the laws of the states they are in. As a liberal I often find that democrats are far to unreasonable about gun control. It's our second amendment. Meant to protect us from our own government. Of course we have a very different society today, so mandatory training and background checks etc should be in place. But there should be no reason why a law abiding citizen shouldn't be able to protect themselves.
