It's important to recognize that all religions are also nothing more than conspiracy theories that have, through the passage of time, settled down into a moderately consistent dogma. Therefore we can't be surprised by the fact that it's frequently religious people who embrace conspiracy theories which is why a huge number of Evangelicals in the USA are devotees of QAnon. Likewise in the 1930s a huge number of Catholics embraced fascist conspiracy theories, believing that Jews were secretly manipulating destiny. People are almost always ignorant and foolish; democracy empowers them to vote for those who most readily lead them by the nose - to their ultimate doom.
