religious issues n.
Questions which seemingly cannot be raised without touching off holy wars, such as "What is the best operating system (or editor, language, architecture, shell, mail reader, news reader)?", "What about that Heinlein guy, eh?", "What should we add to the new Jargon File?" See holy wars; see also theology, bigot.
This term is a prime example of ha ha only serious. People actually develop the most amazing and religiously intense attachments to their tools, even when the tools are intangible. The most constructive thing one can do when one stumbles into the crossfire is mumble Get a life! and leave -- unless, of course, one's own unassailably rational and obviously correct choices are being slammed.
