I agree government has no right telling women what to do with their bodies..... I wonder how men would react if Congress passed a law about surgery on their penises.....
Here's where we part ways (in that I think your analogy falls short).
If abortion was just about a uterus, then the "penis" analogy stands up. But abortion is not about the uterus, it's about the "thing" inhabiting the uterus (or soon to inhabit).
So abortion advocates would be on better ground if they dumped the "my body, my choice" mantra because there is an object inside her body that has DNA different from the woman and that "thing" doesn't get an opportunity to make the same argument/appeal. In today's day and age of anti-bullying, a woman claiming supremacy of "my body, my choice" over the "thing's" "my body, my choice" is the ultimate in bullying (and irony).
A better, more accurate argument would be to claim the "thing" in the uterus is some sort of parasite. But that won't work because it would speak volumes about what the pro-abortion gang truly thinks about humanity and human life. It's also cold and clinical. So they go with the fundamentally inaccurate "my body, my choice" because it has emotional appeal. It also plays as the "I am woman, hear me roar" anecdote to the "women held down by the Patriarchy" and thus, highly persuasive. Because anyone who speaks against it is accused of sexism, misogyny, etc.
I bet they'd be Shechem bent by that.....
Excellent. Making people work for the reference! Well done!
