nota bene: just as how not every male person who uses technology, or is in technology, is a tech bro, not every man who uses linux is a linux bro.
a bro who uses linux boots up his computer and uses linux.
a Linux Bro burbles in the cesspit of the internet, thinks "being clever enough to install linux" is a sign he is a glorious chosen one with infallible intellect, and never stops to consider "hm, what if i'm wrong, actually?"
