Well, I agree, unfortunately. Sabine is smart and knowledgeable, but when people try to engage with her in ways that push the boundaries of her knowledge, and especially when that may be some uncomfortable "unknown" position that we have no certainty on, Sabine will usually (in my observations) double down on her position and refuse to even entertain an outside idea, often in a derisive and short way that cuts off any form of dialogue about the issue.
I don't have examples to hand as it's early and I can't be bothered, those are merely my observations based on a handful of interactions I've seen with her on twitter and adjacent spaces (such as podcasts), and should be taken as such.
Her blog posts criticizing LIGO were based on a series of papers with very obvious flaws. She never addressed that it might have been a mistake to blog about it without talking to experts before.
