Nice strawman equating nonduality with flat earth and other materialistic religions. Top critical thinking, very science and logic.
If you are so sure of your stance, prove to me that matter exists outside consciousness. And good goddess, at least try to do better than pointing at an extracted brain will you? Nonduality has been around for thousands of years and it’s yet to be debunked despite there being a very clear criteria for it.
Can’t do it huh? For all your talk of science, you sure are ready to take the belief in materialism for granted. Just another belief you demand others have, demand others have the same thoughts as you. The road towards fascism is short indeed.
Unless you can provide scientific proof, I have no reason to subscribe your belief system and neither does anyone else. Go read https://www.bernardokastrup.com/ or https://bradleyhook.com/donald-hoffmans-concepts-simplified-understanding-reality-and-perception/, debunk them and you probably have grounds for your ideology. Else, it’s just another house of cards built on a foundation of fiction.
