I have a great deal of respect for people who can walk into a code review and look at their own code objectively as community property.

As do I. Really, I do. Unfortunately, people tend to take it personally sometimes, especially in some languages where code style borders on religion (which is why I speak of Java). I would love to see fair and unbiased code reviews, but you can't do that when the group is not a meritocracy, but rather ruled on seniority and posturing. Having meetings to question code quality can get very ugly unless everyone is on good terms and is in it for the good of the group not the individual. I want the former, but I have been unable to find it (sad, actually).
