I removed the text in question because, as was described in the edit summary, it was irrelevant. The question was about whether the prophet died naturally or if he was poisoned. The question had nothing to do with whether or not Aisha is a reliable narrator which, as best I could tell, was the only point the removed text was trying to explain. Were that the case, it could've easily been replaced with a single sentence stating "However, the Shi'a do not consider Aisha to be a reliable narrator, and as such treat these reports as questionable."
Answers are expected to be clear and focussed on the question asked; this not only helps the questioner himself but also all future users who are looking to find the answer. As such, irrelevant information serves only to lengthen the post and make the actual answer harder to distinguish, which doesn't serve this community or the internet as a whole.
We are not a soapbox. We are (trying to build) a library of high-quality questions and answers.
If someone (be it the questioner himself or a future user) wants to know why the Shi'a don't consider her to be a reliable narrator, that would be an excellent question for the site. Because that's exactly what it is: A completely different question.
And if such a question were asked, explaining the situation in detail as was done would be entirely relevant.
