I'm sure there were many others.
I believe the OP is right, but providing uncontroversial evidence of that is hard. You need a thorough classification of the feedback in a number of sufficiently comparable cases, involving both men and women, to provide hard evidence. And even with hard evidence in hand the conclusions could be ignored; cf. climate change.
This isn't a debate that can be settled by rational evidence.
It's just how the world works. We can all pretend like we don't have uncontroversial evidence and that we'll never know if her identity as a female really affected the response. That's pretty much the status quo. Or we can not be blind and see what's happening right in front of us.
