Both meet the criteria of
- Believe that we are rapidly headed for an end of the world catastrophe
- Believe the only way to avert catastrophe is by everyone in the world suddenly making massive (unrealistic) changes to the way they live and how society functions.
- Seem more interested in evangelizing and catastrophizing than actually convincing people.
- Want to use the power of the state to force others to live in the way that will avert the imminent crises.
- Get incredibly upset when anyone questions, (even well intentioned) their beliefs and proposed solution.
