What is the useful purpose of a swimming pool exactly? Are you proposing that they are a meaningful part of our society? Is this "use" so valuable that it clearly outweighs the deaths it causes? You seem to in your own comment think the bicycle provides the same benefit, so why keep pools if we have such a great alternative? No one swims a gun, but no one swims to work either. At least there are people actually dependent on bikes because they can't afford cars.

So you think pools qualify as a necessary risk then?
Is it at all possible that you may just personally see no use in guns while appreciating the recreational value of a pool despite its risks, while at the exact same time a gun owner may see no use in pools while appreciating the recreational value of guns? You can't swim (useless activity) in a gun. You also can't fire a pool.
I can actually perfectly understand the argument "well, both guns and pools should be outlawed then". I really have a hard time shrugging off pool deaths because they are such a clearly useful thing that is a necessary risk for society though (however that argument works much better for car deaths vs. gun deaths).
Edit: Below I was just commenting on understanding your audience and thus not making arguments that won't resonate with them. There is an entire culture around gun ownership. There are some people that go shooting every day, and it really hurts your position to tell them that that part of their life is not a valid "use". It is actually quite similar to football in some respects. At some point in this country we may have to discuss the very real health issues associated with it, and a part of the framing of that argument should probably not belittle the attachment people have to something that is in fact quite useless (as any and all recreations are to the people that don't practice them).
