There is such a thing as righteous judgment, but it seems that lately the word 'judgment' has become a curse word, period. The issue isn't whether or not we're insightful enough to avoid being judgmental, but whether or not we're secure enough to accept being judged. It is inevitable for every conscious human being to judge. It may spring from insight and experience and sincerity, and in such cases, it is quite beneficial on the receiving end.
