To be fair, that kind of violent outburst can be seen on both sides of the debate. There are the crazy Mac fans, and then there are the crazy Apple haters, and any thread on Apple (positive or negative) is bound to attract both. Unfortunately, both camps contain some of the loudest members of the tech population and are utterly convinced their "side" is right, so inevitably their back-and-forth nonsense drowns out the quieter majority of reasonable users.
I guess this could be said of nearly any issue, really.
