Hello Gentlemen...
Wow, what a spicy story!
I don't know how I feel about it on some levels.
Private life is private... if kept that way. I think it might be the case that if this woman really was able to keep her identity a secret, and/or if she weren't on the Internet and was only doing whatever she does at home, then it shouldn't matter what she does. That IS separate from her life as a teacher.
Questions I have include... did she teach her students anything about sex, or her own sexual values? Did she show them slide shows? Did she give them the website URL?
I think the fine line here might be quite hard to define. Morality isn't universal -- although the concept of morality is -- so to judge her actions isn't really an option. But society's standards would seem to indicate that maybe she ought to be either teaching older people who most likely wouldn't be as apt to be influenced one way or the other or the other, or not to teach.
I'm conflicted here, because I do think sexuality is a personal issue and should never come into play when discussing abilities in other areas. But it would seem that once it's out on the Internet, it's no longer your own issue only, but everyone's. And that is a choice she made, it didn't just happen by accident.
