To use, ironically, a religious analogy....It's like we are all on a "religious" board that believes in the same God, but have different denominations. If I am Catholic, I am not going to point out all the negatives of my fellow forum mates that are Baptist. Nor am I going to point out the negatives of my own faith. The goal is "God".
Again, just an analogy, I am by no means saying this is a religious forum, of course :-)
