Transhumanism is not the reason why people are leaving religion. Nor is it lefties. Or communism. Or capitalism. Or Nationalism. Or fascismI'm quite certain the jury is out on whether either of those situations play out in that way, though I expect the answer to be moot, as we've almost certainly passed the peak of the trend towards weird lefty transhumanism and instead see a surge in young people increasingly finding religion.
It's very specifically religion itself that is destroying itself. And here I'm limiting this to the institutions. But expanding it to include all religions. If religions got rid of it's institution and just engaged with the people, everyone would benefit
