Wikipedia:Articles for deletion/Steven M. Greer
Yes, he is a proponent of fringe conspiracy theories but he appears to be notable since there is sufficient coverage of him by reliable sources. GoogleNews gives 70 hitshttp://news.google.com/archivesearch?hl=en&um=1&tab=wn&q=%22Steven+Greer%22+ufo&ie=UTF-8 for ''"Steven Greer" ufo''. Most of them contain nontrivial coverage of Greer personally and his activities and often provide some brief biographical info as well (e.g. references to him as a former emergency room physician). GoogleBooks gives 49 hitshttp://books.google.com/books?q=%22Steven%20Greer%22%20ufo&hl=en&um=1&sa=N&tab=np for the same search. I think this does satisfy :" If the depth of coverage is not substantial, then multiple independent sources may be needed to prove notability; trivial coverage of a subject by secondary sources may not be sufficient to establish notability". In this case there is a fair amount of nontrivial coverage over an extended period of time. I would say that he passes
