I wouldn't call that answer a frame challenge.
Roughly what proportion of people think that abortion should be allowed, even if fetuses are persons?
Frame challenge: those are inconsistently applied, not just by society, but frequently by the same people.
So the question asks for something to be quantified. Your response doesn't attempt to quantify anything. Nor is it clear what frame you are challenging. Does the question claim that people are applying principles logically and consistently? If anything, it seems to be saying that they aren't. Your response is thus a reiteration of the assumption of the question, a frame reinforcement rather than a challenge.
Also, what do military engagements and legal executions have to do with abortion? Nothing. Which is part of what suggests to me that your real point was that this isn't the only policy area where people are inconsistent. But that's not the framing of the question. The questions asks only how many people take this seemingly inconsistent position on this particular issue. Pointing out that there are other people taking inconsistent positions on similar issues doesn't address that.
