Why do good programmers need strong opinions? (Score 3, Insightful)

This is a serious question. I totally agree on every point except that a "great programmer is uncomfortable using a technology he doesn't feel is right". Two developers can be great but be completely at odds. Wouldn't the 'better' programmer say, "Perhaps I don't feel right because I don't know enough about it?" Strong opinions about certain technologies, in my experience, signifies a degree of ignorance and imbalance; and they didn't learn it correctly, extensively, or in the right context. In my opinion, a great programmer is more open-minded, allowing a non-biased filter to consider technologies he doesn't "feel is right." Am I right?
