You can't ignore it these days. In public facilities well beyond schools, the heat is on to have all- gender bathrooms. In New York City it will come quicker but I wonder not about the office buildings and museums but about the small businesses where announcing toilets are open to all is anathema to the culture.
Already in Watertown last week, the pastor of a Baptist church declared from the pulpit, no way, no how to people using anything other than the bathroom of their birth.
It's an issue that would arise so seldom in most places, who cares ? Except will employees object to using such bathrooms ? Anyplace like a church where children are present is going to have flash points.
In mandating a solution to a problem that largely doesn't exist, it's possible more problems of different types will arise.
