Holy shit, stitching the two halves of that post together involves so much stretching I'm going to call you Dhalsim.
People's brains are chunks of meat. Of COURSE it occasionally happens that, after thinking about things in a certain way for a while, humans think about these things in all new ways because of the miracle of chaos that has resulted in meat that thinks.
The key thing here is that, when a realization is made through altered or unaltered states, that realization is a culmination of learning that has occurred within that human's lifetime and direct experience. Dex and all rational people say that there is no external consciousness or spiritual memory of a time when we were all One that any human is tapping into, they are merely reordering the information they have taken in through their meat brain and spitting out something else, which will either be correct or not. More often, not.
I don't really think Dhalsim wants to say that humans can share a collective memory. I really do think he is trying to agree with us, but is still insistent on using Buddhist language to do so despite everyone having proven their collective refusal to engage on that plane.
But then he said "I'm saying in a material sense people can be a helluvalot smarter and more rational than they seem to an outsider, even when they express themselves in something "irrational" like religious language.", which makes it sound AGAIN like he's trying to claim scientific cosmological knowledge for primitive buddhist morons, so I don't even fuckin know anymore I guess.
Hey desp! Straight up! Does realization come from personal experience, or spiritual collective memory? One of these is the right answer!
