I think there's a fair point to be made that some gender norms around friendliness in women are often misconstrued by men as flirtatious. Or put another way, women are expected to behave in a more "flirty" way, or they're seen as cold and bitchy. But if they do act more flirty, they're seen as "leading men on".

I think the technical term for this is "Some Grade A Bullshit", but it's been a while since I read a sociology textbook.

None of this really has anything to do with the case at hand though.
