I see why you would want to remove ego, but there's nothing wrong in admitting subjectivity. Unfortunately, it's difficult to be completely objective in every topic one discusses, specially because of biases we are even unaware of, and because not every argument is objective. Sometimes we have opinions that we interpret as facts and sometimes the subject is an inseparable part of the discussed topic.
You may make subjective remarks of opinions (especially positive ones, those are good in a code review and may improve team spirit), but don't confuse them with actual criticism.

Yeah, I guess I was thinking of general feedback, more than specifically criticism.
