I'd say try to get involved with your local racing association. Ours here in Washington is the WSBA (www.wsba.org) and topics like this are discussed at the meetings. Try to get a group of women who race and who would like to race involved too. If the organizers see that there is enough interest they might start to change their minds, but it takes people who are willing to fight for it too. A lot of organizers feel like women's racing isn't big enough and that they lose money on it.

We are starting to have the same fights over women's cat 3's here now (which is great, because it means we have enough 3's to put up a fuss!). Organizers complain that they don't have enough time and that its too expensive to hold separate races, the officials think its too complex to score a combined field separately (I say BS they do it just fine down in Oregon). I think attitudes will change, but change is slow.
