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 .
That's the right way to take criticism, despite the tone of the person criticizing you or your post, you shouldn't take that personally and start personal conflicts between yourself and senior forum users because you won't get anything positive out of that. Even if a newbie thinks that they aren't wrong and are being criticized without any reason, they are still supposed to accept the criticism and respond with respect because that will show how mannerly they are.
You don't get small or lose your respect if someone criticizes you and accept it with grace. So newbies need not take this personally and just respond with respect so that they are given more respect the next time by the same users that have criticized them earlier.
