Also, people who are prejudiced against certain groups (or against specific behaviors by those groups) might claim to be creeped out by those people, while giving a reason that seems entirely distinct from their prejudice. It might not even be at all conscious.

E.g. if a woman is assertive and has strong opinions, people are more likely to say that the woman is being rude than if a man had exactly the same behaviors. In a man, they might even consider those traits admirable. It's not at all a given that the complainers even realize that they have a double standard - to them, the woman simply comes off as rude while the man comes off as strong-willed and charismatic.
