I think one of the things that contributed to the "rising star" narrative was the use of social media and other transgender activists from other parties (Lily Madigan, Sarah Brown, Heather Peto etc.) working to support AC in the Greens. So AC had little support from the electorate, a bit more from the Greens, but lots of support from the wider Transgender Machine.
AC benefitted from Lily Madigan's exposure in the media and became The Green Lily Madigan.
This raised AC's profile and so the Stonewall gigs and talking to Parliament stuff came flooding in. The media gigs were only ever about transgender of course; AC was never booked to talk about green policies. I'm guessing that AC has never actually read up on green policies.
The Transgender Machine loyalty is much stronger than any loyalty to the political party. For example, Lily Madigan (Labour) teamed up with Sarah Brown (Lib Dem) in order to harass Ann Sinnott (Labour councillor) on Twitter.
