Women know how often they find men creepy. Statistically this would make their lives ones capable of being perpetrators.
Women therefore want to believe that the men in their own lives couldn't possible be creepy.
Women will therefore excuse any behaviour that is similar to that which their loved ones display.
And are therefore quick to point out any flaws in themselves which they believe led the creeps to them.
The over all effect is victim blaming but the initial sentiment makes me think of madame bucket/bouquet.
I see the same dynamic in men but it also seems to be a question of running away from a tarred brush.
I honestly don't think any thought is given to the victim per-se. They are just collateral damage in self preservation....
