Yes, there are a lot of questions tagged as history on Skeptics.SE. Especially when it concerns historical matters involving religion, it's not clear which sources are valid on Skeptics.SE.
For example, the community wiki on meta List of useful sources for Skeptics.SE does not provide specifications for either category of A) history or B) topics involving religion.
Certain topics historically attract bias and conflict of interest (such as topics with scientific and religious interfaces)--there's just no way around that. This site needs a specification for dealing with such topics because this site is full of such questions (observable upon reviewing available question tags).
Can anyone offer here proposed improvements to the acceptable sources spec?
