According to a commentator, TERFs lobbied UK Gov to stop companies from building gender neutral toilets

The full comment was this:

The TERFs successfully lobbied the previous government to make exclusively gender neutral toilets illegal under Part T of the building code. Because exclusively gender neutral toilets don’t discriminate against anybody and would therefore be acceptable to trans people and if the TERFs went dishonest far-right cranks, it would have presumably been on with them too, and it would have ended the culture war. That’s why they had them banned, because it wasn’t about toilets, changing rooms or sports, it was about keeping the culture war going to make life impossible for trans people.

So this is not just a clerical ramification, but a genocidal move. See my other comment.
