Environmentalism would be naturally good, in essence (it smells like JJ Rousseau illusions), and manipulation by fear would only be a sign of its manipulation by the bad guys
. In this case, it will be necessary to clearly eliminate the manipulators of fear who act through environmentalism. Greta Thunberg, Al Gore ...
I don't know if you are aware that your position has something religious about it. For believers, God is good, so if on earth it is bad, it is man's fault. This is what Christians have been telling us for centuries, making men feel guilty. Famines and epidemics were divine punishments because man did not conform sufficiently to the dogmas of the Church.
Today rebels with ecologism. It suffices to replace "God" by "Nature", and we have exactly the same thing. Nature is beautiful and clean, and man messed up everything. Reheating ? his fault, and his punishment! Pollution ? his fault, and his punishment! Enter all my very dear brothers in the Church of Ecologism, scrupulously follow its dogmas, propagate its good word, and we the high priests promise you paradise for you and your children. Otherwise, they tell us as the Christians told us, your life will be hell, that of murderous pollution and the heatwave that will cook us like merguez on the barbecue, until the species disappears. .
When you say that the "system" that I would defend manipulates ecologism, it is the type of position that the Catholic hierarchy had saying that the devil is there who tempts us and manipulates us.
The enemy is designated, the consumer society that tempts us, the savior is designated, ecology of which ecologism would be the temple, and what each has to do is established: follow the good word of the environmental savior, but of the "real" eh, not devils who would manipulate him. At this level of Manichaeism, I'd be kidding if I didn't know that so many people are ready to swallow this message like choir boys.
