@FBM,
Since the christian vandalism began about two years ago, that is no longer something you can count on at Wikipedia. Initially, they re-wrote entire articles, and editors would come along and simply replace the new text with the previous text. So they got smarter, and simply edited text by removing what was offensive to them, and inserting the "truth" as they thought it ought to read. That was more insidious, because they were no longer technically vandalizing the articles. One response has been to insert "citation needed" tags in the text, and the vandals will go to the talk page to complain about that ("volunteer" editors cannot remove tags). But it's getting worse. This sort of vandalism is now showing up in articles which have political or ideological content, and even scientific or historical articles (conservatives have been attempting to re-write history for several generations now).
The old, idealistic days of Wikipedia seem now to be gone--and probably forever. People are no longer interested in anything which might be called truth--they have agendas, and they intend to forward them.
