Last night there was a thread, in a different forum, named: "The best way to carry concealed weapon (or similar to this)". Everybody was talking about equipment and positions for better carry.
I being old school 2nd Amendment posted: "the best way is without a permit, if they know you have one it's not concealed". I also stated, "too many people died for our right, and not to rationalize our 2nd Amendment".
Yes. Any "state requirements" in order to exercise a constitutionally protected right is an infringement.
This is a good case of using our enemies' tactics against them. Look at it this way. They used creeping incrementalism on us for decades. Chipped away at our rights in pieces so small most people didn't realize they were adding up. So, when WE started the carry revolution about 20 years ago, we snuck it in by saying; "Look it will only be people who have submitted to a background check, given their fingerprints, and taken a class. It's not like we are asking you to let EVERYONE carry a gun." and they grudgingly accepted it.
