I like to frame it like this: "ask me later" is rape culture. It promotes and reinforces a culture of never taking "no" for an answer, and pushing one's agenda/intent regardless of the preference/consent of the other party/parties.
I see the point you're making but this sort of hyperbole has a tendency to turn people away from whatever point you're trying to make unless they already agree with you.
I was visiting a girlfriend once, and she was in the process of moving in the same city. There was a telephone bill on top of her dresser, and I noticed that she had noted "butt-rape fee" next to one of the line items there.
Now she is a very literate woman and loves poetry and "Penny Dreadfuls", so she uses language and words very deliberately. And so, I asked her why she wrote that, and she said it was some sort of unnecessary fee that they were charging to move her line from one address to another, and she clearly resented their opportunistic capitalism.
I certainly sympathized with her, especially since she is the type of woman who has probably been subjected to that sort of actual trauma in her own life, and that of her friends, she had every right to compare the experiences.
