Because th long term survival of our species does not depend on gun control. Mass shootings kill few people relative to just about anything. All deaths by rifles and shotguns are still fewer than those by blunt object. We could allow hand grenades and rpgs and still survive as a species. We are harder to kill than roaches. All that said, I am in favor of limiting the number of gums per month that can be purchased to slow mule purhases. And expanding unrecorded background checks universally to the point I can/must do one on my phone if I want to do a private sale.
