This board doesn't function the same way as the rest of the board. That is by design. People are allowed a lot more freedom to be assholes to each other. But, there are lines that cant be crossed.
Like, jspchief said, If you have to ask or don't know what those lines are, you need to pull the hostility back a notch.
People who think they know everything are a great annoyance to those of us who do.
