Did a bit of analysis of the arguments to not comply..
The most common argument was political refusal or defiance, with 16 substantive arguments, or about 31% of the visible commenters counted. These commenters were not mainly trying to make a technical legal point. They were saying that complying would feel like participating in their own exclusion, so they would refuse on principle.
The second most common argument was avoidance or workaround, with 13 substantive arguments, or about 25%. These people were saying they might avoid public toilets, workplaces, hospitals, gyms, changing rooms, or other sex-separated spaces altogether, or use disabled or single-user facilities where possible. This is not really compliance in the positive sense. It is more withdrawal, avoidance, or trying to get through daily life without confrontation.
The third most common argument was identity-based refusal, with 12 substantive arguments, or about 23%. These commenters argued that they are women or men, and therefore will continue using the spaces that match their gender identity rather than their biological sex. The point being made is that they do not accept the premise that they belong in spaces separated by birth sex.
The fourth most common argument was that the rules apply to providers, not individuals, with 11 substantive arguments, or about 21%. This was the clearest practical or legal argument in the thread. They were saying the guidance tells organisations how to manage toilets, changing rooms, and single-sex services, but does not directly require individual trans people to self-exclude.
Joint fifth were two arguments, each with 10 substantive arguments, or about 19% each. One was unenforceability, meaning staff cannot reliably identify, challenge, or prove someone’s sex in real time, so the rules will be very hard to enforce in practice. The other was safety or fear of harm, meaning some commenters believe using birth-sex spaces would expose them to harassment, outing, confrontation, or violence, so they will use whichever space they feel safest in.
