"Your body, my choice" does not rise to the level of an imminent threat of violence or lawless behavior. It's certainly not "fighting words" as defined by SCOTUS. Without an immediate threat of violence, you do not have a legal right to use physical force. Even in states with 'make my day' laws, this is absolutely not something you can respond to with violence.
I am not an attorney, I am not your attorney, and I would strongly suggest that you consult with a competent criminal defense attorney before you take this course of action.
I'm not a big fan of enticing others to committing murder or useless violence (it's been brought up in other threats), ball busting rapists, or potential rapist misogynists however is a completely acceptable passtime.
By choosing to respond to 'your body, my choice' you're also validating it as a statement that needs discussion or response. It doesn't need either. It's a bizarre statement that's meant to provoke. If you don't like the polarization that's happening, don't let yourself be provoked, don't engage, ignore unworthy nonsense. Responding with hatred, however well deserved you think it is, does not help us transcend polarization, it's just another step in the polarization dance.
Not sure I'm 100% convinced of the above sentiment, ignoring it could make things worse too, hatred does sometimes need rebuttal and just ignoring it could be dangerous too. Still I'm wondering if this would be the right approach. I think perhaps it would help if we would not let ourselves be provoked, take a deep breath, and respond in a matter of fact way, that's not snarky, that's devoid of any sense of hatred, that's not exciting, perhaps even boring but honest and true.
You know, I wrote it kind as a flippant comment, not expecting anyone to pay attention (because, really, who pays attention to me?) and suddenly it's all over the place.
Anyway, I already responded to a lot of people who commented on the original post. I eventually had to mute it due to too much traffic. So if you want to see more, go look at what people were telling me over there. I don't disagree with most of it, and I think having a good discussion on the subject of this is probably a good thing.
Kicking a man in the nuts who wants to harm you (rape or murder makes not difference), doesn't work. It only makes them more aggressive. People tried and failed.
