How dare you point out that the overwhelming majority of mass shootings are committed by men? What are you, some kind of bigoted misandrist?
(That's how it's supposed to be done here at ISF, right?)
The point for many of us is that nobody should be able to commit mass shootings because firearms should be much harder to buy and possess, as they are almost everywhere else in the world except delightful places like Yemen and Afghanistan. You wouldn't need to single out your disfavored groups if nobody was shooting anybody.
