At the event? If so, that's reassuring to hear. Although I have heard KJW advocate for watchful waiting in adolescents who are confused about gender identity, I've also seen footage of KJW saying that children should learn about gender identity in schools. I would not expect a parent to get a balanced view by following up with KJW as any kind of neutral "expert" here. If this kind of issue can be course-corrected at the time that it happens (which it sounds like it was), that is also helpful when it plays out in the discourse.
And on the general thread:
I'm not in a position to have a view on whether Christian nationalist/MAGA teaming has been happening or not on X in recent times. But it's definitely something that I'm mindful of because the UK "GC" demographic is very different from a significant proportion of those in the US, and I wouldn't want to be part of a conflation if this were to happen. The Bud Light boycott was an example of this IMO, in that there seemed to be a lot of straight men distancing themselves from a marketing campaign which threatened their "manliness", because of their sexist/homophobic/(transphobic?) views. I keep it in mind in the same way as I do with any other forced-teaming potential.
It's possible to agree on a point that someone makes without it being complicit agreement of everything that they say. It's also possible to work together, from different GC viewpoints, with a goal to mitigate the impact of "capture" when it comes to gender identity bias slipping through the net when the discussion is widened to include trans identified people.
The way in which the OP has been spoken to on this thread makes little sense, even in the context that there are apparently back stories to the JCJ quoted tweet. I had hoped it might get unpicked productively, in a similar way to the one that followed the Genspect "dress gate" issue but that doesn't seem to be the case so I'll drop off.
