Kri, on Wikipedia we do not treat fringe views in the same way that we treat mainstream views.  Mainstream views are typically presented without fringe commentary.  However, the reverse is not true at all.  Fringe views are frequently subject to considerable criticism from mainstream sources.

This is a mainstream article and WP:UNDUE dictates that it is to be free from fringe commentary.  Conversely, Michael Cremo’s claims should not be presented to the reader without criticism from mainstream sources.  This has the dual function of preserving the integrity of Wikipedia and also preventing every article from becoming an “article about a controversy” style article like Shakespeare authorship question or Ancient Egyptian race controversy.

And believe me; you do NOT want every article to be like Ancient Egyptian race controversy.  76.107.171.90
