There is such a thing as unnecessary comments and I only add comments myself when factors outside of the immediately visible code are effecting the logical flow... but removing other people's comments (other then auto-doc style ones) is a really bad habit. You're essentially invalidating the opinion of whoever thought it was important to put a comment there in the first place and, unless it's done after a team discussion on the types of comments to include in code, it's being done unilaterally.
