That's a terrible analogy since doing something that any reasonable person, regardless of their faith, could agree was foolish and dangerous is obviously not the same thing as telling someone not to join an organization you don't happen to like. You seemed to have missed some of the meat of NOTADVOCATE as well, so I will reproduce the section I was attempting to bring to your attention here, with bolding added to the pertinent words: 
 Wikipedia is not a soapbox, a battleground, or a vehicle for propaganda, advertising and showcasing. This applies to articles, categories, templates, talk page discussions, and user pages. Therefore, content hosted in Wikipedia is not for: 
 Advocacy, propaganda, or recruitment of any kind: commercial, political, religious, national, sports-related, or otherwise. An article can report objectively about such things, as long as an attempt is made to describe the topic from a neutral point of view. You might wish to start a blog or visit a forum if you want to convince people of the merits of your favorite views.  
 I hope this clarifies matters for you.
