I'm not saying this is a valid reason to ban the sale of these items. (Sell anything, so long as you make clear warnings about non-obvious risks. Thus, a chainsaw doesn't need much warnings, because it's a chainsaw. But little magnetic balls which are very appealing to children but also dangerous - yep, give them some clear warnings.)
I kind of agree. That's why I mentioned chainsaws. This instruction manuel for a Stihl chainsaw is, I think, good. There are many pages of warnings. Most of them are informative and address real problems - page 4 talks about why this chainsaw is a special use saw. There are no "Don't hold the wrong end" warnings here.
Some things are dangerous. Everyone can reasonably know they're dangerous, and we don't need to withdraw those items from sale. Other items are dangerous, but those dangers are not obvious, and even though we put warnings on the objects we still find people being harmed.
Again, I'm not sure that harm is enough to force some items off the market. Maybe just bigger, better, warnings.
I think it's much less likely that you actually mean this, and more likely that you haven't read much about the CPSC's side of this story.
Anyway, I was referring to tptacek's apparent failure to consider that someone might think some finite number of deaths acceptable.
The only ways out (that I can see) are to either talk about the disagreement itself or ignore each other and go back to lobbyist fights.
