Choosing One's Restroom, Legally

JUST SO I DON'T MISUNDERSTAND - Today, President Obama, or more properly his spokespeople, shall, and probably already have sent forth a communication to every public school district in America, reminding them that it is a bad idea to break federal laws, and that federal law requires that children be allowed to use whichever restroom he or she chooses, according to whichever gender he or she thinks she is. Scarcely had the edict-warning been handed out when Obama's legion of Christian conservative Obama-haters were out in full force, defiantly declaring their intention of ignoring the president-Dept. of Justice, sneering at the thought of losing several billion dollars of federal money. Hundreds of thousands of American adults have apparently changed their gender through surgical procedures which most of us probably don't even want to think about. So it perhaps shouldn't seem surprising that there are children in our midst who haven't yet gone that far, but might like to, because they do not believe that they are the gender listed on their birth certificate. How many, is anyone's guess. To my knowledge, comprehensive surveys have not been made. It seems highly unlikely that anyone would make it up, just to get attention. Mustn't we assume that all these gender switching people are for real? Can you even imagine the torment they must go through internally? Then comes to hard part; the external torment. Wouldn't it be helpful if the federal government sent out warnings to us all, regularly, reminding us that it is a bad idea to break the law? Nothing could straighten me up more. Does President Obama have reason to think that, beginning now, public schools might start refusing to allow kids to use the restroom of their choice? How has it ever come to this?
