It is important that we help transgender children along their transition, or they can end up committing suicide like the many that have in the past.
This is not a new concept, in fact, transgendered children have been doing this since the beginning of time. People fail to remember this ever being an issue, because it wasn't an issue. Until North Carolina's HB2, this was totally acceptable and legal. The problem arose when HB2 decided to start governing the bathroom to -air parentheses- "protect the children", when in reality they were simply banning transgendered individuals from using the bathroom and locker room that they have been using since they were children.
When the governments of states want to start limiting the rights of others, the federal government steps in to put a stop to it. This is what Obama is doing, to prevent any further trauma to transgendered children.
This trauma includes having to use a restroom and locker room that does not fit them, increasing the risk for further self-image issues, bullying, and further isolation. Children who are transgendered suffer tremendously in schools, we cannot add to their suffering.
Now, I do see how this can be an open door for deviant boys who want to just peep on the girls, but being able to use the girls' rooms would require the teenage boy to actually identify as a female. From what I know about children and adolescent psychological development, this is a huge barrier. Boys in school age will not say they are female simply to spy on the girls, and I bet the girls would not do the same. Also, you don't just wake up one day and say, "I think I want to be a boy/girl." The transgender students would have already been identified and schools would most likely be contacted about issues that they face by parents.
This is again, a case of fear mongering by the mass media. Think for yourselves and you will see that this is an act to protect children, not put them at further risk.
