>>the rabid Java fans I've worked with [closed mindedness]

It is hard to argue against anecdotal evidence, but of the cases you mention -- java, Rails, Django -- imho, it is not exactly the Java people who seem to be the worst language/framework fanatics...

(That said, scripting languages eat static languages' lunch for development speed in most every case I've seen.)

That kind of framework enthusiasm doesn't really stem from the closed minded mindset I was referring to. Most Ruby & Python devs I've met would admit that Java is a much better choice than their perspective languages for something like that requires distributed concurrency and speed (like Cassandra or Redis). The people I'm talking about are the ones that wouldn't look seriously at RabbitMQ because it's written in Erlang, not Java.

I got your point, I wrote that according to my personal experience the other cases are quite a bit worse. Which is worth as much as your personal stories.
