>>3085908They base the nickname on Gen Z being more conservative based on certain studies, such as a Hispanic Heritage Foundation poll which showed high schoolers voting majority for Trump in a mock election. But other studies show them being more liberal, such as a Scholastic poll of high schools which showed students voting more for Hillary in a different mock election.
These studies all have 1,000 respondents each so it's hard to tell if Gen Z is majority conservative or liberal yet, but /pol/ is jumping the gun already.
