Concealed carry permits and constitutional carry are all states rights issues and are being handled at the state level, largely by being able to vote in elected officials that will change those laws.
When did we get to vote on who gets hired by the ATF to make these kinds of regulations? Did you get to vote for/against Chipman? My ballots must have been lost in the mail. The brace ban is being done by a federal agency and affects everyone in all 50 states. We have an anti gun president who in his first 6 months in office is charging hard towards another AWB. Chipman is about to be head of the ATF, a guy who is an anti gun zealot who works for anti gun organizations. This isn't going to stop at braces and no matter how much you and others like to point the finger at gun owners for being at fault, it doesn't change the fact that they won't stop.
If you're okay with a govt agency telling 10-40 million gun owners that they're about to be felons overnight for a legally purchased piece of plastic, something they've allowed to be sold for more than 9 years, then you and I have very different ideas about what a govt agency should be permitted to do.
