I think there are many different tiers here. There are:
1. Don't believe the climate is changing period.
2. Believe the climate is changing.
3. Believe the climate is changing but believe only a tiny part of the change is due to mankind.
4. Believe the climate is changing and believe only a medium part of the change is due to mankind.
5. Believe the climate is changing and believe its solely due to mankind.
6. Believe the climate is changing and believe is solely due to mankind and that our government will fix it with taxes.
7. Believe the climate is changing and believe is solely due to mankind and that our government will fix it with taxes, and the main threat are farmers.
8. 6. Believe the climate is changing and believe is solely due to mankind and that our government will fix it with taxes and the main threat are farmers, and the people who will fix it own multiple houses, fly private planes.
9. etc etc etc etc.
10. Greta Thunburg flying all over the world to tell people how dare they live a less decadent life than her.
The issue with the cult is that you aren't at least a 6, preferably higher, you are usually called a "denier". Which is what I believe you are guilty of.
so much of it is not actual denial of the situation, but rejection of the messaging and the way the people who preach the message react to the threat.
