If you were not speaking to any fundamental differences, then why did you start your post with:
And I have issue accepting the "I was talking about a subsection of the prochoice group compared to the pro-life people" argument. The post you were quoting did not break it down into some small subsection, your post did not pair it down to some subsection, it was only after your assertion was called out that you've suddenly tried to rephrase it in a different fashion.
And no, that is not a FUNDAMENTAL difference between the two. If it is, then pro-choice individuals would feel the same way with regards to child abuse laws as they do about abortion...it's the parent's "choice" and we (the public) have no right to "impose" our point of view on that upon someone else.
But that's not the fundamental different, because by and large most people who are politically pro-choice have no issue with laws regarding child abuse, child neglect, and things like that. Just as it can't be said that fundamentally, those who are politically pro-life fundamentally believe the government should decide on peoples health care, since there are a variety of instances where that is likely not the case with those people.
When talking about the FUNDAMENTAL difference between the two groups, it entirely comes down to how they feel the law should view the fetus as it relates to rights. That is the delineating line between the two sides and is the ultimate arbiter for how they form their political views. And in both instances, those views are generally pretty logically consistent with that view.
As to your questions, based on what you've been saying, I'd suggest you're a predominantly pro-choice person who personally decided against having an abortion.
