The subject of this article has been going on for centuries, most among farm kids. It's gross, like picking your boogers and eating them, but not something that we need a law against, nor something that will bring down civilization.
Right. There is no one action that will bring down a civilization. But as all the single actions add up they form one heck of big whole that can (and has) destroyed empires. But that is the way it works, isn't it? Each of the single actions is unworthy of more than passing attention. It is only when we look back and examine the wreckage that we can make a determination as to what they all added up to.
