In a forum like this where so many intellects are contributing to a particular discussion there is always a room for criticism and the ability for you as newbie to absorb it as a learning process makes you unique and smart . For me Criticism is a process of learning because when ever I am been criticised I usually seize the opportunity to add more knowledge because I often see it as a corrective measures to widen my horizon .
Given that it's a forum and everyone has the right to voice their opinions on any subject under debate, there is room for criticism.
Almost all of the members of this forum have received criticism in one form or another, whether it be constructive or detrimental. High ranking users have also experienced criticism because this is a forum where everyone is subject to criticism.
Both positive and negative criticism is crucial to learning; the first will boost your happiness while the opposite should push you further because nobody is an expert, so the main purpose of negative criticism is to motivate us to study more and build our self-confidence.
