Factivist
A kid or a brain-dead adult who just repeats what their activist group tells them, like a robot. They spread fake news and make everyone around them cringe.
"They told me to say the sky is purple, so I did. Now I look like a fool.", at a family dinner.
DM: "You’re not cool unless you believe the sky is purple.", from a kid who can’t spell cool.
At the Thanksgiving table: "The sky is purple, and I believe it!", while the rest of the family is eating.
