PrideAlliance is open to all queer Alliance members and sympathetic socialists. Queer is defined in a broad sense, including people who identify as gay, lesbian, bisexual, polyamorous, asexual, kinky, transgendered, or otherwise in violation of heterosexual gender stereotypes (with the proviso that only consenting adults are involved, of course!), along with sympathisers such as straight partners of bisexuals.
Members are encouraged to join the Alliance Party as well, but it isn't compulsory. Alliance membership is an option on the PrideAlliance membership form.
The membership form is available here in pdf format. If you have trouble with this, email us.
