I never used to have issues with people who had been in porn becoming teachers, or working with kids, but that was when it was usually some old video done under a fake name that was unlikely to actually be seen by any kids. It's significantly different to have people working with children who are actively doing "sex work", or posting pornographic and/or fetish content and sharing it on their public social media. One is a part of someone's life that they've tried to move on from; the other is a continuing, active choice.
This makes me think of all those stories: "Years ago I did porn and now I'm a schoolteacher/nurse. Some student / coworker recognized me, told everyone I did porn, I got harassed and then *I* got fired for it."
It's as if these people either don't recall being hormone-fueled horndogs as teenagers or are deliberately taking advantage of the fact that their audience
is all hormone-fueled horndogs now (since these fuckers are practically always pedophiles, you can probably guess which option I'm going with).
I only had a few physically attractive teachers back in high school, and I was already distracted enough with how they looked
clothed to make it modestly difficult to pay attention in their classes. I'm 100% certain I could never have taken any of those teachers seriously again if I knew what their tits or cooch looked like. It would have been impossible to concentrate on anything but matching the clothed body in front of me with the photos/videos in my memory. And I know I'm not the only teenager who would have reacted like that.
The absolute state of the world these days
Take heart, friend. This thread lit up like a Christmas tree a couple days ago when they finally started actually seeing real-world consequences for these actions! This is actual accountability for once! We're nowhere near the finish line but people are finally starting to stir from their collective slumber, even if only a little bit. And these perverts aren't doing what they should be doing in response to this. They're escalating and doubling down instead, which is the exact opposite of what they should be doing (i.e. policing their own, disavowing the obvious pervs, shutting their fucking mouths and backing off the kids for a few years) if they wanted public opinion to stop slowly swinging back towards sanity again.
Just look at the new movie 'bros' which has a scene defending exposing a minor (<14 in fact) to a gay sex show in order to help him come to terms with and get more comfortable with his sexuality. Used as an excuse in an in-story debate about whether (why) it's OK to talk about letter people crap and overt sexuality to school children! There is NOTHING anyone can say that will make me look at the involvement of these types of people with both porn and children, as being harmlessly incidental.. Sorry, that ship has sailed by LONG ago!
And you're correct. Anyone who wants to show pornography to someone (or a group) that's underage is universally a pervert and likely pedophile. There is
zero reason for anyone to expose a child who isn't their own to pornography, and it's even suspect when a parent or guardian does it intentionally except maybe to address a child's genuine curiosity. Even then, it should be brief and accompanied by an explanation (as
@nym rightly points out).
It's one thing for a fifteen year old to share a pornhub URL with his similarly-aged friends, but it's quite another for a teacher in their twenties or thirties to show a classroom full of 15-year-olds a high-definition video of a DVDA scene with "BLACKED.COM" boldly emblazoned in the bottom right corner. There's only one reason anyone would ever do that -- desensitizing children to sex acts and grooming them to be comfortable hearing about, witnessing or even participating in them.
It should be so simple. At some point they're approaching puberty, you're not only gonna have to sit the kid down and have that "birds & bees" discussion but at some point not long after "you're gonna see this porn stuff..."
Sadly, I think we need to start adding some more provisos to your (very sage) list here of how to prepare kids for pornography. I can think of at least one: "if someone besides us tries to show you pornography, especially an adult, like a teacher, school official, counselor, or whatever, stay away from them, stay on your guard, and tell us as soon as you can. We won't be mad at you and you won't be in any trouble at all for it."
Parents need to start warning kids that this shit's coming, potentially even supposedly trustworthy adults, and they need to know it's absolutely acceptable (and encouraged!) to narc on the perverts who try it. Kids who aren't afraid to ask their parents awkward questions about sex are already very well prepared for this, so it's every parent's job to make sure that's true for their own kids.
