why is it that people insist on answering question incorrectly and using their opinion as fact?

Because the majority of the people who use this site to answer questions do it to give themselves feel a false feeling of importance, and have no lives. I, of course, am an exception. My brilliant answers illuminate the universe!

Rather than complaining about the quality of the answers that you read on this site (and some of the answers are truly horrible) why don't you take the opportunity to add to, or edit the bad answers, and post better answers. This is a group effort. If we do our part, there will be better answers.
