"Smoking and firearms are among the leading causes of avoidable premature death in the United States"
The statement is true for smoking but it takes some work to make it true for firearms. And then it describes tobacco and firearms as "both are legal yet lethal" - it borders on nonsensical to pair them that way (I guess possessing both can be legal, but it's worded to imply that the use of both, in the ways that resulted in death, is legal).
I'd love to see fewer firearm deaths, but it just seems odd to try and link a really high cause of deaths with one that is an order of magnitude smaller, while skipping over others that are very preventable causes of death. You are, for example, many times more likely to die from poor diet than from being shot. I mean, using their framing, automobiles are "legal yet lethal" and auto deaths are the cause of about as many deaths as firearm deaths - and that includes suicide (i.e. intentional) deaths.
