I think it's noteworthy that we couldn't even keep a metadiscussion of this topic completely civil. This shouldn't surprise anyone. "Don't bring up religion or politics"; it's a rule of etiquette (and probably the most common bit of advice in the "Respect" section of every page on WikiVoyage). Why do we think we're exempt?
It's very difficult to talk about, because it's important and people have strongly held beliefs. Respect that, and the purpose of this site.
