These “climate” terrorists should be forced to live in a mud hut in Africa. No running water, either.
You know, that’s my thought on all those “No fossil fuel” types.
Pick an island, uninhabited, but with a suitable climate for growing food. Provide seed, some farm animals, and perhaps some tools. No steel, though. It’ll need to be handcrafted wood and stone.
Drop them on it. Nothing goes with them that needed fossil fuels. They can make their own utopia without it. After a year in their paradise, we can see if they are ready to rejoin society as productive member.
