I think you're applying the concept of telling the tale in public rather broadly. This is, in fact, a public forum, in that anyone on the internet can come along and read it...but they don't. The people who do are those who understand the humor...why it is(n't) funny, and why it's necessary. I would never tell dead baby stories/jokes to my great aunt Mae, but I'll tell it them to the "strangers" on this board, because I figure they'll get them for what they really are, and it helps to blow it off. I'll read theirs because they help me to read, just that little bit.
Depending on the the comments, someone could have reason to make an example of what is said. The reality is that people do come by and read posts here and some folks use this site as a source of information about EMS. This is evidenced by folks that sign up and ask questions because they're interested in the profession for work, or because they're looking for understand when writing fiction, and so-on. Forums have become a source for news reporting. In Philly, it was domelights.com (a police and fire forum) - site was shutdown and lawsuits were filed. Fortunately, I haven't seen any thing posted here (on any topic) that is anywhere near as vile as what was posted there. But, my point is that forums like this can suddenly become "interesting" to someone else. The moderators are pretty good here, but nonetheless, we should tread carefully with especially sensitive topics such as mental illness.
