This is just a website. It is not your life. The other posters are just people. Excellent karma will not let you live longer, or make more money. This is like a game, but less important, less interesting, and less fun. Metamoderate if you must, but try not to take this crap so seriously. If you feel greivously offended by the moderation made to your comment, then you probably value your own opinion too much. If you always check the moderation that has been made to your comments, or read the responses, then you probably need a higher workload, a hobby, or a pet.
So many people have journal entries where they whine about the moderation system. So I have decided to have my own journal entry where I whine about these people.
