I'm confused..one would think a transgendered person would not want attention drawn to their new sexual identity. With the ACLU tampering with their Rights regarding bathroom use and bringing attention to what one would think a private issue would seem more problematic. What's wrong with.."don't ask, don't tell"?  Just use the bathroom that fits your trans gender...no one will know and why should they, unless you want them to and why would you? 

 To bring attention to this topic in the early grades would be most difficult. Taking natural biology and standing it on it's head to "become" the opposite sex is a big order to embrace for preadolescents and yet the ACLU in some cases is pushing for special education and bathroom policies in the early grades.
