I don't doubt that you had sex ed. I do doubt the veracity of your claim as to its content.
I know this is shocking to some, but sex education in this country used to be far more about the science and facts of reproduction and sexual behavior than it is today. The politics (on both sides) have transformed it into a collection of teachings designed to tie into a given political position on related issues and *not* to teach strong facts about the issue itself. Believe it or not, they did talk about issues like rape, incest, homosexuality, and how those things intersected with pregnancy, STDs, etc even back in grade school. I hit the whole run of sex ed twice because I attended a public grade school, and then went to a religious middle and high school. Public schools taught sex education in 5th and 6th grade back then. The religious school I attended did their first intro stuff in 7th, with the followup in 8th grade.
Couple year difference aside, the information provided was more or less identical in both schools. Yes. Complete with relatively boring films, which seemed the popular education technique of the day.
Young people today like to think they are more progressive, better informed, and more open minded than past generations, but in a lot of ways, they are more coddled, less well educated, and less well exposed to real diversity of ideas than their parents. They just don't realize it. We spend a lot more time and effort talking
about how we should handle these subjects, but honestly a lot less actually doing it. This is a general observation btw, not just about sex ed. The same can be said about nearly every subject taught in our education system today. We're so concerned about exposing kids to something too early, or offending their parents, or hurting their fragile sense of self esteem, but we just don't teach them in a factual manner anymore. We no longer expect responsibility from students, so we don't teach them as though they can be responsible enough to handle the lessons. We coddle them and protect them from education. And then we wonder why they don't have a freaking clue how the world works after they graduate.
