I note, as does the article, that the information sheet is from 2019. At the very least, this shows a lack of care following the SC ruling, or a lack of interest in checking these things (which is more worrying). But, it reeks of activism still embedded in some of these individual groups, if not the entire organization. Parents with girls in GG will need to be vigilant, as apparently GG will not be.
The fact that Stonewall doubled down on support for "kindness" when they should have been commenting on why they are still allowing information that they contributed to in 2019 to be used in 2026, says quite a bit about them.
As we've pointed out before, non-binary is one of the only avenues left to activists, along with conversion therapy, and working to change the EA to include "gender identity" without clear definitions. (See also the current thread about Stormont "debating " gender identities in NI). Expect to see more "non- binary" as the "female" and "male" routes have now been closed down by law.
