Operating system (or OS) advocacy is one of the primary pastimes of people who have a deep and abiding interest in the design, construction and usage of computer operating systems. For these people, the investment necessary -- both in money and time -- to own and operate a computer creates an emotional investment in the operating system of choice. Such advocacy turns to arguments, as people compare and contrast the virtues and faults of different operating systems. Arguments between advocates of similar systems sink to the level of ongoing, vitriolic, and personal attacks; such arguments are known as the "Holy Wars". Some "Holy Wars" include Windows vs. MacOS, Windows vs. Linux, Linux vs. BSD. Some wars of the past included VMS vs. Unix. There are related wars over programming languages and text editors.
