Historically a lot of useless dogma and arguments have surrounded the choice of editor. There is a desire to avoid that sort of low-quality discussion.

The Emacs/vi/IntelliJ/Eclipse/Netbeans/Kate/jEdit/TextPad debate is meaningless, because all the above choices are "good enough". However, a decent programmer's productivity will be severely hampered by Notepad. Similarly, the Rails/Django/Pylons debate is pointless, but choosing JSF can easily kill your project.

To the extent that it becomes a religious discussion about which one is the best, which happens all the time, I think you're right. However, the exchange of ideas that results can be meaningful. This is especially true of emacs, since there's so much room to use it creatively, but is applicable to all those other editors as well.
