...it's very difficult to remain radical and transgressive all the time because the system is continually adapting to accommodate you, so you have to continually step outside that moment of transgression to a further moment of transgression and keep pushing.
This competitive edginess is about money and about trying to stay relevant to keep getting funding and about being the "coolest" kid in the room. Stonewall adopted the trans cause for the same reasons. When same-sex marriage became law, that was an example of "the system adapting to accommodate you" and so Stonewall stepped outside of LGB rights into trans activism to "keep pushing". Same-sex marriage was the last legal hurdle to LGB people having the same rights as straight people and so the Marriage (Same Sex Couples) Act 2013 meant that Stonewall no longer had a purpose. This would have been a great time for the trustees to set up some mechanism to protect Stonewall's legacy (perhaps by endowing a museum or library to document the gay liberation struggle) and shut up shop. But, that would mean the CEO and other staff having to find other jobs. So they adopted trans activism to extend the life of the organisation, maintain the funding, and keep those people paid.
This "queering", this perennial escalation of demands via endless "transgression", is to politics what capitalism is to economics. Capitalism relies on creating a demand for a product that didn't exist five minutes ago. Queering relies on creating a demand for alleged "rights" that no one even thought of five minutes ago. At the root of both is money and perceived status.
