I came across this link by accident while looking for an example for another thread.

It is increasingly common, particularly in LGBT organisations, that groups for lesbians are open to men who identify as women some of the time (ie natal males who identify as heterosexual men for most of the week but identify as lesbian women part-time and attend lesbian support/social groups and events). This is increasingly explicitly stated on event leaflets etc, although even where it isn't, no one would dare question anyone who turned up on their gender identity.
The organisation linked above is one that subscribes to this view, as stated on that page, and says that it doesn't knowingly list organisations or support groups which 'discriminate'.
As organisations like Women's Aid and Rape Crisis are listed, how widely are these other organisations defining 'woman' now? Can "part-time women" get access to women's refuges and rape support groups as well now?
