As @R0wantree linked to on the thread on crossing out 'gender' for 'sex' on school forms, but this deserves its own thread.
Take a look at 'BISH' website for teens.
www.bishuk.com/about-you/whats-your-gender/
Has a helpful diagram. People called 'he' and who look masculine tend to be tough, active and independent. People called 'she' and who look feminine tend to be soft, emotional and passive.
He goes into schools and youth clubs and gives training to teachers on sex and relationship education with this shit! bishtraining.com/
"Our genitals are on a spectrum in terms of: how much erectile tissue sticks out (clitorises and dicks and inbetween); where the prostate is; where the wee hole is; whether the gonads are inside or outside; vagina size. Many people are in the middle of this spectrum with how their bodies are configured."
WTAF? There is a spectrum as to where the prostate is? that makes just as much sense as saying there is a spectrum as to where the uterus is between males and females ! 
"Currently I’m heavily involved in the DO … project. This is a campaign to make great sex and relationships education happen in schools." www.dosreforschools.com/
BISH and the DO SRE FOR SCHOOLS project are both sponsored by Durex and DO involves serious people who know about biology like the Family Planning Association, Brook and the National Association of Headteachers.
....I hope they were just not paying attention. I think we could bring it to the attention of their twitter accounts that they are supporting the promotion of sexism and absolute biological nonsense into schools.
