I suppose we could take this to another level and ask why the females are called wo- men and fe-males as if they are a sub section of men rather than part of a pair of people.
I've always interpreted the name as implying it's a men's team with women tolerated, and the club's gender ratio would support that assumption.
I can understand that the word seems to imply men and less so women. I have to say, though, that the ratio of men to women might just be because more men are interested in archery than women.
I wonder how many enquiries about joining archery clubs, that are made by women, include a question like... "And are women allowed to join?" I think that would be a common question if the word "bowmen" was in the club's name and women felt they might be excluded.
In years to come, if words like Bowmen became universally used to include both genders ... rather like " doctor"..... would that not help with equality? If two words are used, one for each gender.. does that not indicate differences are understood which might continue the unequal treatment. So for example "doctor" and "lady doctor" suggests differences where use of " doctor " alone, suggests equality.
