That's the point, you shouldn't have to give up one to get the other. That's why your entire scenarios was idiotic.
If you want to make ridiculous demands in your scenario, don't get bent out of shape when I decide to make analogies, which is what I did.
If you are willing to support abortion, that means you should have to wear a sign, saying you think it's fine if someone kills you, if they don't want you. All's fair, right?
Mind you, I think abortion should be legal, I'm just pointing out how ridiculous your scenarios was.
