LKa couple of thoughts  Its counter productive to call someones good faith efforts WPagf to improve an article ie reverting your edits vandalism  Think twice before making that claim  please read WPnpov carefully  I am not going to debate whether Islam and yellowstone can be reliably sourced but I will contend that its a topic that will violate undue weight of our NPOV policy when seen in the light of the yellowstone article and is unlikely to be allowed to remain  There are s of tidbits of content that could be added to article but arent because of undue weight  Again please consider drafting an independent article on the subject and if it can pass muster can surely be linked to the main article     LK
