When the Act was being written, do you think it was ever imagined that it would allow for absurdities such as shown in the link?

In a nutshell a woman identifying as a man but still being in possession of a vagina (in other words a woman) was asked to leave the sauna because it is only licensed for gay men.
From the report “In a statement, Sailors Sauna said: "We are only licensed for men to use the venue.
"I understand that the gentleman was male, however his physical gender was different and as a customer had already stated that a female was using the venue, I explained that I would need to clarify with the council.”
‘He’ wasn’t male. She is female.
The Act allows this state of affairs to exist – but sometimes the law is wrong.
