Very true. Reminded me of Parkinson's law of triviality, which is
an observation about the human tendency to devote a great deal of time to unimportant details while crucial matters go unattended.
I have experience working with highly opinionated people, was one of those myself actually. Almost every code review was a passionate discussion, mostly about trivial things, not always though.
Then I also have recent experience working with people who don't care at all about how X should be done as long as it's working and doesn't look like complete piece of crap. Actually scratch that, most of the project was written like there is no tomorrow.
Nowadays it's somewhere in the middle, which I think is actually a great place to be. Trying to make a uniform code style for a team is a good effort, nothing wrong with that. Giving suggestions about why X should be done as Y (e.g. it's easier to read or less error prone) is fine.
But I think one should always remember that the code we write as stable and long lasting as a fictional sitcom family. Or enriched uranium. Being too opinionated, to the point where only your opinion is the answer, is very stressful for everyone involved, even the person himself.
