My son is in elementary school and had a "sex ed" lesson a few weeks ago. He told he learned about transgenders. My wife and I werent aware he'd be learning that and we were a tad "weirded out" by it (and we're pretty open minded people)
Welcome to 2019. Cant wait to see what the next decade has in store for us!!
K-5 sounds kind of young to start sex ed. (to be honest, I didnt read the full article as of typing this) 5-6th sound about right though. I think the way to look at it is as if it was sex ed / sociology. Sex ed isnt just penis/vagina. Its anatomy, hygiene, and socio-sexual lessons. (manners, dating, general non anatomical info). I dont know how the lesson in question went but I have a few friends that are gym teachers / coaches in middle and high school and I have actually asked them about this. When the portion of gender (rather than sex - anatomy based) they review the trans, cross, bi, etc as more of a "hey this exists out there". More or less a vocabulary lesson and then move on. They are out there, they exist, bc you dont like or agree with what they do... it doesnt matter. Lets face it, your opinion of a certain group has no bearing on them and wont change anything. The average person will come across members of those groups sooner or later and what the kids are taught is vocabulary and take away the "shock" factor for when the time comes for them interact in the real world.
Thats just what the small group of people I have talked to about it had to say.
