Religion isn't an essential component of fascist ideology. Indeed, religion to a fascist is only a rhetorical device. Whether it be the Positive Christianity of Nazi Germany or the evangelical movement in the United States, fascists tend to ignore or rewrite religious doctrines that are inconvenient to the regime, while overemphasizing the importance of scripture that reinforces fascist ideology.
@burnoutqueen the difference with global warming causing the societal disturbances this time is if the fascist win globally, the will inherit an uninhabitable planet.
