Yeah this is a reason I think this is dumb. Who decides what a woman is here? Australia doesn't even have bathroom laws discriminating against trans people as far as I know. How do they enforce this, by just telling people who they think look too much like a man to leave? By asking for their ID and only allowing in people who legally changed their gender?
Women's safe spaces are important. This is not how to do it.
Is this the intent of the artist? Are they making a statement about gender identity? Was the baseless discrimination the art all along? This specific article doesn't make it clear to me, but maybe I missed something.
