A Life Lesson
IT IS EASIER TO BE AN ASSHOLE TO WORDS THAN TO PEOPLE. The people you chat with on the internet are real people with faces, shoes (sometimes), fingers, and everything. They have feelings just like you and your beloved pets. When involved in a discussion or argument with another user, it is imperative that you remember this, and behave accordingly.
Being abusive to others is not acceptable. In reality, some ops care about this more than others; it is in your own interest (in addition to the interest of those around you) to behave as if whichever op is present will care a great deal.
