The risk being truly, mathematically zero is different from "don't worry about it."
I agree with you in principle, really, I do. Let me use the "drop side crib deaths epidemic" as an illustration.
From the period of 2000-2011, the vast majority of all US babies who slept in cribs (i.e. many millions per year) used drop side cribs. In this same time period, there were 32 deaths of babies blamed on said cribs.
This is a mortality rate so far below 1% that, scientifically, it deserves no more than a footnote at the bottom of a study, if that. However, WE GOTS TO POTECT THA CHILRENS, especially those of people who don't use common sense (read details of those deaths, and in almost all cases, the root cause was parental negligence).
Again, from a purely scientific perspective, I would state that drop side cribs are safe if used with even a drop of common sense. The risk is greater than zero, but far, far less than, say, riding in a car.
All I am asking the "OMG HOMEBREW CAN KILL YOU I CANNOT BE CONVINCED OTHERWISE, FACTS BE DAMNED" contrarians is to show me one real world case. Not 32 over ten plus years, just one.
If you find one such case, I'll roll my eyes at you and ignore you for the sensationalist that you are, but I will freely admit that the "homebrew CANNOT hurt you" argument falls into the realm of "don't worry about it", not "the chance is zero."
So again, one real world case. Just one.
