You are making a ton of assumptions about the nature of confidence, attraction, and sexism, which potentially reveal your own biases. For one thing, I don't think that confidence and placing someone on a pedestal are "polar opposites" of each other, rather they are entirely different and uncorrelated dimensions of personality that can exist in any combination.
There are models of behavior describing personality across cultures, like Hofstede's Cultural Dimensions, that speak more broadly on the way a group behaves as a whole. You might want to give them a read.
They did not claim that "confidence" and "placing women on a pedestal" are polar opposites.
They claimed that "being sexist in front of a woman" and "lacking confidence" are polar opposites.
They also claimed that "being sexist in front of a woman" and "placing women on a pedestal" are polar opposites.
Do you disagree with their actual claims?
Apologies for possible pedantry. I think their actual claims are actually compatible with "confidence" and "pedestal-placing" being different dimensions.
