But don't think that people who believe that a woman can harm a man don't believe in this trope, oh no. For those people, there is the belief that any man who is being abused by a woman must have done something to deserve it, because Females Are More Innocent and Women Are Wiser, so they would never resort to using violence against another living thing unless absolutely necessary.
The consequence of this line of thought is this trope. A man raped by an attractive woman is considered a lucky man, and a man being raped by an unattractive woman is comedy gold.
"To put it simply: men are neither supposed nor allowed to be dependent. They are expected to take care of others and themselves. And when they cannot or will not do it, then the assumption at the heart of the culture is that they are somehow less than men and therefore unworthy of help. An irony asserts itself: by being in need of help, men forfeit the right to it."
