First and foremost you are born female or Male, so all these different surgically induced genders are irrelevant to natural human anatomy, so why would we teach children about the choice to falsely alternate that anatomy. Secondly, I personally feel that by teaching young children that they can be any gender they want will confuse them. I'm not by any means against LGBT, however, transgender started as a rare physiological belief that a gender was born in the wrong body but now that it's become acceptable more people are changing their genders not because they feel as though they were born in the wrong body but because "monkey see monkey do" in other words more people are doing it simply because they have the option. Additionally we all know that kids are not capable of handling or understanding sexuality, hints the laws on sex with minors. With that being said what makes people think that kids under the age of 18 would be able to process that information without influencing them or confusing them........... if this really goes into affect I can promise if I ever have kids they most certainly will not end up in the public school systems
