White supremacist accelerationism is a school of thought within some segments of the white supremacist movement (primarily neo-Nazi and alt-right white supremacists) that argues that, because white supremacists seem unable to reform or reshape modern society to fit their desires, the only alternative is to use violence to destabilize and destroy society itself, with the hopes of building a white ethnostate in the chaotic aftermath.  Non-accelerationist white supremacists are divided on using violence as a tactic, but accelerationists wholeheartedly support it. The perpetrators of a number of recent white supremacist-related mass killings or attempted mass killings around the world have had links to accelerationism.  Some other right-wing extremists have occasionally used the term more generically, to describe destroying the status quo or established order. The term "accelerationist" can also be found in other contexts, such as left-wing social theory, where it has very different meanings.
