agreed but what about the kid that is in there and sees something that is foreign and how do you protect against that? Not to mentionm those who would take advantage of this and prey upon people
How does it change anything?
There isn't anything currently in place to stop a predatory man from walking into the ladies' room. Allowing transgendered people into the ladies room doesn't really change anything other than enshrining into law what almost certainly happens now. And why would a child see anything - if someone is in a cubicle with the door closed nobody else sees what they are doing.
If a child sees someone coming in to use the bathroom why would they thing anything is foreign? If you force people to use the bathroom that corresponds to their birth gender you're far more likely to create other issues - how would you explain to a six-year-old boy why the person who just went into the stall in the men's room is wearing a dress and makeup? How would you explain to a six-year-old girl why the person with a beard is using the ladies' room? If people go into the bathroom, pick a cubicle and close the door, where is the problem with children in the first place? The person who comes in wearing the dress might have been born female, they might have been born male and transitioned to being female. Maybe they are a man who just likes to dress in women's clothing. But whatever is under the dress is hidden because they do what they need to do behind a closed door.
If anything it makes it harder to prey upon people when everyone uses a unisex room. With traditional rules in place (i.e. use the bathroom based on your gender at birth), a man going into the women's room has either made a mistake or is looking to take advantage of someone. An honest mistake doesn't need legislation; the man looking to take advantage can be fairly sure he is unlikely to face serious opposition. But what if everyone is in the same room, only separated by cubicle walls? Now if you go in hoping to take advantage of a vulnerable women you've almost certainly got other men around, maybe even the woman's husband or boyfriend. So instead of tackling a 150-pound woman you might be facing a 150-pound woman and her 250-pound weightlifting boyfriend.
Those who look to prey on people aren't going to worry too much about existing laws anyway, so it's not as if new legislation really changes anything.
