It's relevant because it's about a youth not being accepted for how they are or how they see themselves, and suffering accordingly. Similar to a transgender young person whose parents may not want to come to terms with their transgenderism.

Steve. you're a man and most likely have a different standpoint to that of women who feel that 'their' spaces should be respected. A Ladies' toilet is a sanctum, where women can see to their make-up, adjust their clothes, seek reassurance from their friends and so on.

I would definitely not want to be in a female toilet (not just the cubicle but the washbasin area and, if young, using the sanitary products dispenser etc) when a person who is physically a man (even though presenting as a woman) walks in and claims the space too. I would be ill-at-ease and a little afraid to be honest.

Of course, this problem is easily solved with individual toilets that are unisex, each with a washbasin etc, but that costs a lot more to provide.   

If 'antideluvian' is too kind a word for me Steve, I have every confidence in your ability to find a far more insulting epithet.
