Gender Neutral Toilets - Why?

Gender Neutral Toilets - Why?

If gender neutral toilets are the answer, what is the question? The justification appears to be persons who do not identify themselves according to binary genders. How common is that? Are gender neutral toilets needed for them? Do they desire to use them? Do gender neutral toilets make them feel safer?

Apparently, it is incorrect to state that gender neutral toilets are for transgender people, or for a "third sex". Which just leaves me confused.

I genuinely don't know why gender neutral toilets are necessary. I do wonder if the provision of gender neutral toilets is an attempt to challenge the widely accepted notion of gender binarity. Social engineering, in other words.
