Are you implying that someone who prefers Eclipse is more likely to be a good software engineer than someone who prefers Emacs? If so, that is so hilariously backwards that I can't even begin to understand the types of experiences that you must've had.

I am sure that you're objectively wrong if that is what you're saying.

I'm reading it as: those unwilling to try both and make an honest evaluation and instead have preconceived notions and bigotry tend to make bad programmers. That preferences are fine, but dogmatism should be avoided.
