Agree, but I'm interested to understand how relevant their intervention would be.
I can understand why an interest group would need to make the argument that a swimming facility should be single sex (It's quite unusual for a swimming pool to be single sex all the time), and I can understand that some people believe that associations should be free to choose how they organise because of freedom of association rights.
However, I can't understand how a service can meet the criteria for excluding men, but include any man who wants to use the service. On what grounds would they be excluding people? It was clear that the 'Man Friday' was organised as a protest, but what if one just turned up? Would the decision be vibes based?
Anyway, I think it can only be a good thing for people to make arguments in public.
