I think you're misconstruing comments critical of Kennedy.
The issue is that he's a climate fanatic, and catastrophic CO2 warming is the prime ideology behind the Great Reset. Just because he doesn't say much about this doesn't mean he isn't 100% on board the catastrophe ideology.
Kennedy can set things up for the next phase of the Reset: the climate emergency requiring emergency powers.
Catastrophic CO2 warming is the monster waiting in the wings.
