I am speaking from my personal experience of having been in several schools over years. I never saw anyone telling their students to go out and have sex and I never saw anyone advocating their students to have abortions. Perhaps other school systems have that sort of thing going on, but kids would have gotten back to the administration about teachers saying stuff like that and word would have gotten around. In the hundreds of faculty meetings I've attended, no mention of "do not suggest having an abortion in class" was made, nor "do not tell your students it's OK to go out and have sex". Perhaps some of the new young amoral teachers they're hiring now would say stuff like that, but no one that I personally know would. Matter of fact, the people that I know would most assuredly tell the students quite the opposite, in an effort for them to develop some self-esteem. "Don't feel like you have to give in when your boyfriend tells you that if you loved him, you'd let him have sex with you" or any of those other oldie but goodie lines. "Have some respect for yourself and tell a guy like that to hit the road" would be more in line with what my colleagues would say.
There’s a world of difference between what an individual teacher may tell some students and what official policy is.
