The Duncan League (DL) has been given the duty of righting all the wrongs of the past. Although they are often assumed by outsiders to have similarities to the Social Justice Warrior (SJW) movement, they maintain no affiliations with any national or local chapters of SJW, and are on the whole slightly younger than the first-wave SJWs, although an overlap with second-wave SJWs may materialize in the future.
It was believed to have been started in retaliation to the Anti Duncan League, which are a bad user. Because two double negatives cancel each other out, a cop told them they had to call themselves simply the "Duncan League". Must have been continental European. Maybe Icelandic, but that's not as likely.
