Cahn's writing argues, in summary: the Stonewall riots of 1969 which launched the modern gay-rights movement opened the floodgates to another realm, from which ancient pagan deities returned to Earth, including the Mesopotamian goddess Ishtar, who is resentful at being marginalized for thousands of years and hungry to return the favour against Christianity.
Reminder: These people are not trying to say anything true. They trumpet deliberate falsehood as a demonstration of power: "Because I can get away with slandering you, I therefore have power over you."
The more absurdly false the lies they tell, the more power they are laying claim to. The right response is laughter and mockery, not rebuttal. They are standing up in front of the public in a clown outfit, proclaiming that foolishness and idiocy must be treated seriously.
