48 out of 50 state constitutions guarantee the right to own firearms for self defense. The two recent SCOTUS cases changed practically nothing - except if you live in DC. It is the least threatened civil liberty. And civil liberties are regulated, BTW. Speech, arguably the most basic, is heavily regulated, from security clearances to speech on the job. You could write a weighty tome on just that.
Compared to habeas corpus, probable cause, voting rights, due process, right to assemble, and separation of church and state, any perceived threat to the 2nd amendment is a fantasy...just like the belief that more guns somehow make us safer and the other NRA advertisements. Never fails to amaze how little of a shit the Right cares about all of the above except their cherished right to kill another human being.
