I don't know, it sounded like improving GH's diversity/inclusivity was exactly the reason she was hired and so that must have seemed like an obvious place where she could contribute. And she didn't call the data scientist transphobic or made any personal remarks, she just corrected her. I'm not saying I agree with everything she did, but based on that incident I'd say the data scientist was the one who handled it poorly.
we don't know the exact phrasing, but considering she "called the data scientist out on her transphobic survey" does imply she indirectly insulted the data scientist
