A female would use the women's room. She'd go sit in the stall and pee, even if she could use a urinal. Your daughter has nothing to worry about.
I think the only time I have seen it as an issue is these weird forms of protest... http://komonews.com/news/local/man-found-in-womens-locker-room-cites-new-transgender-bathroom-rule
Bathroom obsession is nothing new. Remember Miss Hillie in The Help saying the maids had to use outhouses because "they have different germs"? During the fight against legal segregation, that was an actual argument, not only would white people be affected by "black diseases" (but not the reverse since whites were so clean and health), white girls and women would be attacked by violent black girls and women in desegregated restrooms. During the fight for Equal Rights Amendment an "argument" against equality was that we would have unisex toilets, you know, like Greyhound buses and airlines, and men would use them to assault women. No one could cite anyone being attacked in an airport bathroom but facts were unimportant, bigotry was. There has not been one single instance of a transgender person assaulting or raping a cisgender person in a public restroom. The opposite, sadly, is not true; transpeople have been assaulted. And there is nothing in the law that stops a man from walking into the ladies' room to assault someone, except that assault is already against the law. How the hell do you enforce this? Genital checks in every public restroom, courtesy of the party of small government and personal responsibility? The cops have already said they have no plans to do so. When asked, state legislators admitted they had no enforcement plan. They just wanted bigotry on the record. The law does much more. It allows anyone to refuse service or employment to any gay or trans person if their "sincere beliefs" tell them to. There can be no penalty for discrimination based on sexual orientation or gender identity/expression. Municipalities that had such laws have found them repealed. While discrimination based on race, religion, national origin, sex, age, or disability is still illegal in North Carolina due to federal law, this law prohibits those who faced such discrimination from filing claims in state court. Federal court is slower and more expensive. A woman whose age/disability claim was under jurisdiction at the time the law passed had her claim dismissed, not on the merits, but because such cases are now prohibited. The law also prohibits any city from raising the minimum wage. What that has to do with keeping girls from being raped in bathrooms I don't know. Charles is right. So is Bruce Springsteen. So is PayPal. It's nothing but bigotry. Hate for hate's sake. A "solution" to a nonexistent problem for the sole purpose of demonizing gays and transpeople. Religious freedom does not mean you can force others to live by the twisted beliefs you call god.
All these so-called "Religious Freedom"/"Bathroom Bills" that keep popping up in red states are nothing more than temper tantrums resulting from the Obergefell marriage equality ruling. The bigoted religious right are beginning to realize their ability to discriminate so freely is being threatened and are acting accordingly. Wonder what they'll try next once these pieces of legislation are inevitably declared unconstitutional.
If someone wants to assault someone of a different gender in a bathroom, I really don't think a law about bathroom use is going to stop them. It is a contrived fear that bathroom laws will cause an increase in assaults.
