More Explanation is Better
It is a fine balance to express one's presuppositions in the question/answer without giving too much background (since there is a lot of background behind each of our views).
Using your question as an example, Jack (who I do happen to know is a Christian) edited out your opening line:
We know that tradition has it that Satan is an over-zealous servant of
the LORD.
Now I see two issues here: (1) since we are all "anonymous" technically on this site, Jack may or may not have known you were coming from a Jewish perspective (I would not, as I have not interacted enough to know that is where you come from). And (2) you included a "we," which implies something about your reader that may not be true. I think (2) is probably more the reason it was edited, though (1) may have been a reason also.
I would not object to you reediting your question, and saying something such as:
My Jewish tradition has it that Satan is an over-zealous servant of
the LORD.
You might want to further qualify who/what you take "Satan" to be. These are clarifying aspects of your presuppositions, and those are perfectly valid as long as you keep it localized to a "my" type statement. (I often clarify in my answers that I come from some particular perspective that relates to that answer). That gives us more context for your question.
Don't Expect Just a Jewish Presuppositional Answer
So now, as a Christian answering, he/she may challenge the presupposition to set forth their answer, but it becomes incumbent upon them to make a case against your presupposition before then further answering the question. They should not merely dismiss your presupposition.
Of course, a Jewish answer may role with the presupposition and answer accordingly.
You may or may not vote up a Christian answer, based on how well they have handled at least making their case against your presupposition. I would assume you would not mark it as "Accepted" unless you were swayed to the Christian point of view regarding the presupposition and the answer.
That is the essence of how I understand the site is to operate in our mixed tradition realm. Both questions and answers need as much clarifying information about the presuppositions involved as necessary to help in answering the question, and all such presuppositions should not be taken for granted as "we" statements, but rather you as an individual, or "we" in clarifying the group referred to (in which case, having a reference that would "prove" you are not the only of that group to think that way may be helpful).
