Just a guess: a fifteen year old who has been taught and believes that intimacy takes place only within marriage is less likely to fall “in love” with a teacher and act on it.
A lot of folks think government and laws are the first line of defense against teacher/student “romances”.
Children are far more knowledgeable about sex at a far younger age than ever before. Our society is awash in sexual stimulation.
I remember as a child most children would not be affected by the “values contrary to the ones taught at home” because they were actually taught those values and internalized them. A post-pubescent child is quite capable of unwisely “falling in love.”
That same child can also have a conscience which protects them against acting upon it.
Does the girl have a father at home? If not, she would be more susceptible to the attentions of an older man.
It’s not like it was when you were a kid. Now there are dozens of stories of teachers raping kids, with a twist. Female teachers are raping adolescent boys, and it’s now common to read about.
Schools don’t bother respecting parent’s values — they are not there to teach so much as to indoctrinate. The Democrats have hijacked the schools, and the private ones are only marginally better.
Dr. Dobson has it right — “pull your kids out of school and homeschool”.
