I'd say the education should revolve around acceptance of people rather than the segregation of people into rigid stereotypes.In reality, teaching 4 year olds that they might have been "born in the wrong body" is bloody awful.
Teaching people there's not 'being manly' and 'being girly' and that you don't have to be one or the other.
I have trans friends, I also have 'butch' female friends who're heterosexual, teaching children to be them and it's ok is the best way forwards without focusing on any agenda
