I understand that the EqA has a protected characteristic of gender reassignment.
As a layperson I assume this means you can't for example refuse to hire someone for being a (binary, vaguely attempting to pass) transwoman, at least not without finding a different justification to point to such as qualifications.
How far does that extend to various "neogenders", e.g., can you refuse to hire someone because they claim to be catgender or cloudgender or something? Can you explicitly write down in the hiring panel notes "applicant was weird and wore cat ears, no hire"? At some point surely employers are allowed to "discriminate" on the grounds of unprofessionalism and personality and I'm wondering if there is any case law / precedent / legislation that covers this case.
