LK-a couple of thoughts. 1) It's counter productive to call someone's good faith efforts WP:agf to improve an article (ie reverting your edits) vandalism.  Think twice before making that claim. 2) please read WP:npov carefully.  I am not going to debate whether Islam and yellowstone can be reliably sourced, but I will contend that it's 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 1,000s of tidbits of content that could be added to article, but aren't 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.
