I could never understand what makes a person think they are helping by critcizing others. I've heard others call it "helpful criticism" but at length it stops being helpful and becomes Destructive Criticism because it tears down self esteem and makes one feel like giving up . It also makes the person you are criticizing develope a strong dislike for you. Also if someone has a different opinion from yours that does not necessarily make that person your enemy. They just see things differently, that's all. It Is So Far Still A Free Country.
