Grand Theft Auto Online
Although Rockstar Games have shut many down, there are still many racist crews in GTA Online. Neo-Nazis and neo-Confederates are the most common of the hate mongering crews, with the outfit of the Ku Klux Klan being the preferred outfit of the latter. Players can dress themselves in similar fashion to that of the KKK outfit by dressing in white clothes and wearing a white pointy hat.
