GDPR is another consideration they need to take seriously. Presumably the 'gender marker' they hold for members is held on a database somewhere. Gender is not on the list of permitted data that an organisation can legally hold so they are likely to be in breach of GDPR and maybe liable for a large fine.
Do you have a link for the permitted data categories? I can feel another email to my HR department coming on.
The Data Protection Act governs our rules re. GDPR. I did find a slightly more general page but the below info specifies what information an employer can hold about an employee (which because of that relationship is presumably more or the same as data that can be held by a club about a member).
This is a good starting point for the full info (sorry I haven't got time to find more atm) but it seems to be quite clear that gender and gender identity are not on any list of data that an organisation are permitted to hold about an individual. I also found an article about the fines/consequences of breaching GDPR rules - apparently the fines can be significant.

Employers can keep the following data about their employees without their permission:
name
address
date of birth
sex
education and qualifications
work experience
National Insurance number
tax code
emergency contact details
employment history with the organisation
employment terms and conditions (eg pay, hours of work, holidays, benefits, absence)
any accidents connected with work
any training taken
any disciplinary action
There is stronger legal protection for more sensitive information, such as:
race
ethnic background
political opinions
religious beliefs
trade union membership
genetics
biometrics (where used for identification)
health
sex life or orientation
There are separate safeguards for personal data relating to criminal convictions and offences.
