 ===Looking at the sources.=== 
 :::::I think the best thing to do at this point is the list all of the sources that you find questionable and we can decide what stays and what goes.  I do think that a lot of it should go, but I feel that some of the claims that you've removed fall squarely into the ""unlikely to be challenged"" category.  (Of course, that's obviously not true since you removed them, but whatever.)     

 :[1] x Harper Collins Dictionary of Philosophy: what is this referencing? There's no page number or entry description. 
 :[2] ? Mapping Reality: the books.goog page is not loading for me 
 :[3] ? Like Rolling Uphill: if the publisher is trusted, these 2 mentions would be good. 
 :[4] x ""alt.atheism FAQ: Usenet group FAQ - like a personal page, blog, or wiki. 
 :[5] ? A Call to Sanity: no quote, the publisher looks dicey. 
 :[6] xx A Call to Sanity Web Forum: web forum, now defunct. 
 :[7] + how about refuting the existence of invisible pink unicorns?: first known Usenet mention. 
 :[8] x h2g2: not a reliable source at all - it's a combination of a blog and a joke encyclopedia (I used to edit there because Adams is my second favorite writer). 
 :[9] + Veracity of Christianity: Usenet post sig. 
 :[10] x Camp: ""It's Beyond Belief"": not pink, article link 404 
 :[11] x The God Delusion: good source, not pink tho 
 :[12] RS Female Bonding: this isn't a bad source, a fluffy ad written as an article, but okay. 
 :[13] x Portrait of the Invisible Pink Unicorn: blog 
 :[14] x The Dragon In My Garage: one of the finest easy to understand pieces written about the illogical beliefs helds by religious people, but doesn't mention the IPU. Fine for an ""other versions"" section once notability for the IPS thru RS is established tho. 
 :[15] x Fall & Redemption Of The Purple Oyster: personal website, not RS. 
 :[16] x The Revelation of St. Bryce the Long-Winded (Partial): personal website, not RS. 
 :[17] x Re: PROVE THAT [...]: this seems dicey to what it's supposed to be referencing.  

  
 :x = not a reliable published, third party source. 
 :RS = reliable source 
 :+ = fine once notability is establisehd thru RSs.  , 2008-10-1421:34z"
