But to tweet something with the connotation of “gun violence isn’t that bad” while ignoring half of the gun violence stats in your own list, and ignoring that there can be multiple problems that can be solved at once (guns, mental health, car dependency, etc.) isn’t the best. I don’t think he’s like objectively a bad person, he’s just overconfident and IMO annoying. He does communicate science though, so props for that.
