Legendary mother live tweets son's pro-abstinence sex ed class.

This mother’s live-tweets of her son’s sex-ed class has gone viral.

When Alice Dreger sat in on her son’s high school sex education class this week, she was outraged.

So Dreger – a medical humanities and bioeithics professor at Northwestern University, author and super cool mum – live-tweeted the whole pro-abstinence lesson from the back of the room.

The class involved horror stories about pre-marital sex leading to depraved and destructive lifestyles, the unreliability of contraception and this take-away message: GOOD GIRLS SAY NO.

Here are some of the highlights…

“You’ll find a good girl. If you find one that says ‘no,’ that’s the one you want.” HE ACTUALLY JUST SAID THAT.

Preg girl got picked on so her friends desserted her. That’s what happens if you have sex, kids! Yup! Pregnant and NO FRIENDS! — Alice Dreger (@AliceDreger) April 15, 2015

She’s now telling story of condom box in which EVERY SINGLE CONDOM HAD A HOLE. — Alice Dreger (@AliceDreger) April 15, 2015

“It takes only 1 sperm to fertilize an egg. It takes only 1 time having sex to get pregnant.” Yet she’s not suggesting oral or anal. — Alice Dreger (@AliceDreger) April 15, 2015

Then came the paper baby disaster demonstration…

“We are going to roll this dice 8 times. Every time your number comes up, in pretend your condom failed and you get a paper baby.” JESUS!!! — Alice Dreger (@AliceDreger) April 15, 2015

Paper babies are being handed out to EVERYONE. They have ALL HAD CONDOM FAILURE AND THE WHOLE CLASS IS PREGNANT.

Yep, even the boys.

“You have to have a baby!” There are apparently no scissors in the room for paper abortions.

Her tweets went viral and have caused a stir back in her hometown of East Lansing, Michigan.

Dreger – who wrote about her experience – said she hoped her experience would encourage other parents to look critically at the sex education their teens are receiving at school, according to the Huffington Post.

The whole lesson here is “sex is part of a terrible lifestyle. Drugs, unemployment, failure to finish school — sex is part of the disaster” — Alice Dreger (@AliceDreger) April 15, 2015

I just want to grab all those kids after school and say HERE IS THE TRUTH. SEX FEELS GOOD. THAT’S WHY YOU SEEK IT. TAKE CARE & HAVE FUN. — Alice Dreger (@AliceDreger) April 15, 2015

“I’m incredibly glad this happened because it is causing a useful national movement of parents planning to audit what is REALLY being taught to their kids,” Dreger said.

“Forget what the curriculum says. Find out what’s true. In our school’s case, I discovered what’s really being taught is ‘good girls say no; bad girls say yes’ and ‘1 in 6 times you have sex with a condom you’ll get pregnant.'”

Now, she says she has been banned from the school because of her “potty mouth”. 

In the meantime I’ve been banned from the high school (except for drop off/pick up/concerts/conferences) for saying ‘fuck’ after class. — Alice Dreger (@AliceDreger) April 16, 2015

It looks like that might be the last time they let a parent in to observe a class.
