Here, lemme answer his four questions:
1. If you believe the 2nd Amendment should be subject to no regulation at all, do you therefore believe all laws prohibiting convicted violent repeat criminals from having guns are unconstitutional? Should all such laws be repealed?
Yes, yes, and yes. It's a whole other can of worms, but basically if you can't be trusted to be a good member of society, you shouldn't have been released from jail anyway.
2. Do you also believe all laws establishing concealed-carry licenses are unconstitutional?
Yes
3. Do you have a concealed-carry license anyway?
Yes
4. Are you thereby violating the Constitution yourself?
No, because I'm not the government, dumbass
