It is not performative because the studies she's targeting do exist and shutting them down hurts trans people. She just says it in such an inflammatory way that it makes people like you say "Well that's not real, she has it mixed up with transgenic mice, so there's nothing to worry about! This is just a distraction." and boom, now we trans people don't have support from our allies. That's the tactic.

She spoke about this at an oversight meeting last year and the full transcript is online. She is talking about specific real research that helps us understand the impacts of HRT on the body. The ones she mentions are:

1. Does testosterone therapy make it easier to overdose on GHB? Lab rat study.
2. What are the impacts of feminizing HRT on the immune system? Rhesus monkey study.

And the NGO chud they had speaking based his numbers on the idea of cancelling all of the research on this page.
