So who are the extremists?
That's subjective, but IMO, the people who go beyond hunting, sport, target practice, and/or a handgun in the nightstand or rifle in the closet (all of which I fully support.)
If you think it should be open carry everywhere, you're an extremist.
If you think restricting people on a terrorist watch list from buying guns is an infringement of rights, you're an extremist.
If you think universal background checks are an infringement of rights, you're an extremist.
If you think banning assault rifles (whatever you want to call them) is an infringement of rights, you're an extremist.
If you think the government is the enemy to a large degree, you're an extremist.
If you are a member of a militia in the mountains based on "white power" or whatever, you're an extremist.
Free speech is not 100% and neither is free use of guns everywhere.
