If you haven't ever been afraid of being beaten, killed, or raped, that doesn't make you a man, that means you have had a very safe life. There is no necessary reason why women must think that. I am certainly not doing ANYTHING to make women rationally afraid of being beaten, killed, or raped, so why should my penis make me responsible for that? Some vague handwavey notion of 'privilege'?
What's up with the jaw thing? Women don't have especially fragile jaws. I guess you are saying that women have especially fragile emotions?
Other way around. It's a bit of a tortured metaphor, but it's not about women being weaker. Men are emotionally insulated by their privilege--it's an extra layer of resilience (the metal jaws) that we take for granted which makes it difficult for us to understand why people without it are having problems.
