Hmm, maybe the last line could be made clearer? Not sure how yet, but this is what the last line is talking about:
The last line of the poem is significant because of its use of two phrases. There's a common phrase men say that goes "not all men are..." and came about as a response to the feminist movement (though very recently). Earlier this year there was a shooting spree where a Men's Rights Activist killed and injured several people, and his reasoning for doing so was that women didn't pay attention to him and wouldn't have sex with him, among other sexist beliefs. This prompted an entire response to his words and actions from women and men alike, and a phrase emerged used by women who argued with men saying "not all men". The opposite phrase used was, "Yes all women". The significance of the phrase being that all women have to treat every random man as if he is a danger to them, regardless if "not all men" are dangerous. So the last line refers to those two phrases and twists them a bit to make a statement about how the narrator as a man can't even help or comfort her because we as men are forced to say "not all men will hurt you" instead of what we as men should be able to say: "yes men won't hurt you".
