In many times and places, the default interpretation of the listeners would have been the playful one, and not the creepy one. It's sad that this appears to not be the case anymore.
Exactly. As a person who once wanted very much to work with teenagers, and saw what it's like today, I can say with no hesitation that anyone who works with kids these days, in this sort of climate, is risking a lot. And it really is very sad.
As a student teacher, I was in a planning period, and a distraught teen girl, my student, came running into the classroom, sobbing. She'd found out that morning her parents were divorcing, and at lunch, her boyfriend broke up with her. I was working with my mentor teachers, and this girl just burst into the room, threw her arms around me, and just bawled.
I disengaged as quickly and gently as I could, because we were instructed never to let students touch us, nor were we to touch them. I comforted her, sent her back to lunch, and got back to my work.
I found out weeks later that my mentors had discussed--with other teachers and student teachers--whether or not to call the cops on me for sexual assault of a minor. From what I was told, they were only just barely talked out of it.
I do not envy anyone who works in any way with children, and I no longer want to, in any capacity.
ETA: that's not to say that nothing is going on with Santa, or that there's not more to his story. I'm only saying there's a kind of hysteria out there, and innocent people get swept up in it very easily.
