Earlier quoted context omitted.
Try rather with: "ask a male nurse". That is more comparable, i.e.: both are perfectly normal, but both are not too common for historical and possibly other reasons.
But I'm not trying to 'balance' anything out. Equality means equal regardless of gender. So if one can have "Ask a female athlete", why not "Ask a male athlete". Your example is valid too. This is a genuine question. How would it be unequal for males to start such a forum for anything they want?

you seem stuck on the "can have" bit, which isn't really the point.
