Just helped an older neighbour sign up for a new email account with gmail. She was asked to input her gender. You can click on Custom and insert your own. Mucking about we put 'Harridan' and gmail accepted it and will now, apparently, tailor her adverts to her Harridan identity. I've since been into my own gmail account and changed my gender to Adult Human Female Harridan.
If anyone can be bothered to do so, do join in. The results will presumably show up in time and make a point.
