Yep, every one of them is wrong — if they endorsed your position that gun control laws can’t reduce gun homicides and mass shootings. I think you should add Jesus and Mother Theresa to the list of celebrities who’ve gotten behind your decision that gun control can’t work here because Americans are too blood-thirsty. Maybe Jesus would do one of his miracles so that your argument is magically transformed into truth.
Be sure to keep your eyes open. You never know what you’ll see.
