Looks like it was all about publicity:
Gay Human Rights Complaint Against Calgary Bishop Dropped - Was All About Getting Media Attention
CALGARY, August (LifeSiteNews.com) - Norm Greenfield, who launched a human rights complaint against Calgary Bishop Fred Henry, has admitted to the media that his actions were done in order to attract media attention. Greenfield launched his complaint after Bishop Henry released a pastoral letter explaining Catholic teaching on the subject of homosexuality. (See the letter here: http://www.lifesite.net/ldn/2005/jan/050113a.html )
A couple of names come to mind for these people, but I will keep them to myself.
