I was just looking up the history of female-only public/workplace toilets, so that I could quote it back to my supposedly-feminist (born in the 1960s, all went to university in the early 1980s) friends who just don't seem to be aware of the the impending erasure of women's rights, and I found this great link:

The message really needs to get out to ALL women, especially in this 100th anniversary year ("Year of the Woman" - yeah right), that we are about to lose so much that previous generations fought for.
