Let me add something to what Caleb has written.
The fact that you use Quran does not always mean you are not ansering from a Shia (or a Sunni) perspective. This is specially true if they disagree about the interpretation of the relevant verses.
When someone asks for a Sunni prereproductive it means they want to know how Sunnis actually view the issue. If you are not a Sunni yourself and your answer is not expressing a view expressed by a Sunni scholar, then you are not expressing a Sunni perspective. It is not sufficient that you base your answer on sources accepted by Sunnis to express an opinion on the issue that is not expressed by them. It won't be a genuine Sunni view.
In summary, if you are not a Sunni and you are not expressing an opinion which is expressed by a Sunni scholar (you should have direct references, not indirect references through say Shia studies of those sources, if you have direct references to Sunni sources expressing the view you should cite them) then you should respect the will of the person asking the question and not answer the question.
Now if your answer is genuinely a Sunni view, then please edit your answer and provide references and then flag it to be undeleted.
PS: the reason the moderator deleted your answer is because he thought that it is not a Sunni perspective and therefore an apologistic answer, and apologistic behavior is forbidden on this site. And it is indeed hard to see that was not the case. Since it is clear that it is not the mainstream Sunni view and many Sunnis would disagree with it, it would have been more appropriate for you to explicitly say that this is the view of the particular Sunni group.
(I agree it would have been more appropriate to ask you first to clarify before deletion, assuming that you don't have a history of appologistic behavior on the site).
