I've found healthy disagreement to be one of the most productive forces in my work. Another few interesting reads on the subject:

I have come to be so uncomfortable with verbal conflict I try very hard to avoid disagreement. I have spent too much time with people who by a combination of inclination, temperament and life skills can "win" any argument, irrespective of the merits of the matter under discussion.

The TL;DR here is that some people prefer winning to win-win even in conversation.
