- Groypers (Wikipedia)
Groypers, sometimes called the Groyper Army, are a group of alt-right and white nationalist activists, provocateurs, and internet trolls. They are notable for their attempts to introduce alt-right politics into mainstream conservatism in the United States, their participation in the January 6 United States Capitol attack and the protests leading up to it, and their extremist views. They have targeted other conservative groups and individuals whose agendas they view as too moderate and insufficiently nationalist. The Groyper movement has been described as white nationalist, homophobic, nativist, fascist, sexist, antisemitic, and an attempt to rebrand the declining alt-right movement.
- Barber paradox (Wikipedia)
The barber paradox is a puzzle derived from Russell’s paradox. It was used by Bertrand Russell as an illustration of the paradox, though he attributes it to an unnamed person who suggested it to him. The puzzle shows that an apparently plausible scenario is logically impossible. Specifically, it describes a barber who is defined such that he both shaves himself and does not shave himself, which implies that no such barber exists.
