I would research the percentage who outright hate a group of people based on race, religion, nationality, sexuality, etc, set it like 5% above that. all neo-Nazis, Daesh, Westboro baptists, 'lock her up' screamers, warmongers. it would be a much more liberal world.....and I wouldn't tell anyone the button could only be used once, so i would be able to set up a gurochan friendly society with myself in charge
