Right, good luck with that. Send them to pre-school a year, then Kindergarten another year, then 12 years spending 8 hours a day with authority figures that have values contrary to what you teach at home - what could go wrong?
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.
