I'm honestly not sure what to make of these quotes in relation to each other, either. For what it's worth, the graphic she puts up in that video reads:

Gender identity - is a category of social identity and refers to an individual’s identification as male, female or, occasionally, some category other than male or female. It is one’s deeply held core sense of being male, female, some of both or neither, and does not always correspond to biological sex.

Which seems to suggest she supports nonbinary identities, but then she declines to defend that view in the Warski video. I'm curious how people more familiar with her work read the situation--I've only just come across her videos today.
