From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Real reason for the hate: The Linux community is overly focused on tribalism and has a console-wars mindset where what I'm using is obviously the best and everything else must be flawed and terrible. Manjaro is probably fine for most use cases.
...although I'd still suggest just using base Arch instead. :)
