It takes a level of maturity to get to this state of mind, and I'm glad for you that you feel this way. So do I.
But it takes some life experience to get there, and it wasn't up to her to provide it.
But in that case, was up to whom? Or in other words: are people to have authorized sexual trainers or what? The state gets to license this service? The state takes its meddling to the logical conclusion and imposes
practical sex education by
licensed teachers?
Think on it, the idea is ridiculous! People must be free to encounter whatever partners they will. Experience cannot come from anywhere else. And - no surprise - people will find partners where they spend a lot of time. High school and later university, for young adults who get into the age of trying sex around, is where they spend a lot of time (incidentally, forced by the state...). Most will go with colleagues, some will go with teachers.
It's inevitable. Of course it must be criminalized when it is with children, they can't consent. It is a grey area with teenagers (and I'm saying teenagers keeping in mind that many countries actually have 16 or in some case even lower ages as ages of consent, and that's not really what we are discussing here) who, let's face it, in this particular case didn't seem to be at all ignorant of what they were getting. So make a rule banning it and fire the teachers who keep violating that rule. And with relations between teachers and adult students, just don't meddle.
And please, about all the talk on this discussion concerning what happens in the military, we should a sense of proportion! It's not the same thing, the training for obedience imposed there is very different from what happens in schools. Don't be disingenuous.
If it was only 1 kid on 1 occasion she would have got a much lighter sentence, but it was multiple counts with multiple students over a protracted period, which obviously means the sentence gets a lot longer. It's the difference between stealing 1 TV from 1 shop 1 time and stealing 100 TVs from 10 different shops over a 10 week period. You're clearly going to get locked up for a lot longer if you do the latter than if you do the former.
Actually, you don't, not in the countries I know of. The notion of re-incidence makes a distinction more about the times you were caught and presented to court than about the times you did something, at least for stuff like petty theft.
But, of course, this wasn't about petty theft, or public urination. It was about....
grand sex? A much more serious criminal offense!
