The BITE classification was invented in order to justify hatred of small religions, by taking a word that already had a meaning (cult) and attaching a second, pejorative meaning to it. It’s like if I write a fantasy novel with a species of evil creatures called jews. Jew is already a word, and it’s a horrific act of religious persecution to take a pre-existing word for marginalised religions and spin it into an unrelated negative.
No, cults are small religions, this is a big religion
They are doing it because it gets people talking and thinking about climate collapse, and that leads to solutions.
