as a native speaker of American English, I assure you that "your body, my choice" is NOT an ambiguous phrase. Subjugation is directly implied. It's a derivative & subversion of a phrase women use to assert bodily autonomy. Like "white lives matter" thing, but frankly worse because there's NO innocuous interpretation without changing his words (which would still be unacceptable, for reasons I stated)
What value is there in pretending that's an ambiguous phrase? Really
