Ok. For the purpose of this game, a non-traditional identity group is anything that doesn’t have a one word or hyphenated term already describing them - because then it wouldn’t be very non-traditional would it? And you have to feel affinity and sympathy for other members of your group on account of their group membership.
So…genders, nationalities and ethnicities won’t get you any points, and neither would ‘introverts’, ‘petrolheads’ or ‘geeks’. ‘People who can’t sing’ works fine, but ‘people with a “rich inner life”’ is probably secretly just ‘daydreamers’.
My non-traditional identity group is: Clueless Vague People Who Really Don’t Know What’s Going On
