and...you still haven't shown us the documentation linking teachers discussing 'masturbation' and K-3 kids....keep digging...don't give up...and don't worry, if you forget, I'll remind you.
I contend it doesn't exist...therefore the onus is on you to produce it and prove to everyone that you are honest in what you post.
btw, attached is a link highlighting the U.S. and other countries data on unwanted teen pregnancies...note that two of the lowest rates are in countries that have embraced Sex & Sexuality Education...here's and excerpt...
----------------------
Compared with young people in the Netherlands, who have the second lowest adolescent pregnancy rate in Europe, U.S. adolescents are faced with greater societal disapproval regarding adolescent sexuality, LESS-CONSISTENT PROVISION OF SEX EDUCATION, and greater socioeconomic inequalities that underlie higher adolescent pregnancy rates among the most disadvantaged groups. (emphasis mine)
----------------------
Time for you to act like an adult and objectively seek out data that addresses real societal problems...instead of hiding your head under the covers.
