The "How to Ask" has "Is your question about scientific skepticism?" (as does the default for the question title), and the FAQ has "Skeptics - Stack Exchange is for skeptics, rationalists, free thinkers, or anyone who questions pseudoscience.".
However, the only answer to Is Skeptics only for pseudoscience, or for pseudohistory and the like? argues that all crackpot theories, including pseudohistory, are on-topic for the site.
Should the "How to Ask" and the FAQ be edited?
