I felt my brain cells dying while reading this.
Some states allow limited exceptions for nunchaku use only in martial arts studios. However, a federal appeals court ruled against a New York resident who argued that the state's nunchuck ban was unconstitutional because it prevented martial artists from training with nunchucks.

The court disagreed with the resident, which meant that New York had a rational basis for banning nunchucks. The court cited the following reasons why New York lawmakers decided to ban nunchucks:

1. Nunchucks are "widely used by muggers and street gangs and ha[ve] been the cause of many serious injuries"; and
2. The bill's sponsor maintained that the nunchaku "is designed primarily as a weapon and has no purpose other than to maim or, in some instances, kill."
WHAT THE FUCK DO YOU THINK FIREARMS ARE FOR, YOU NITWITS?

…Why are nunchucks illegal?
