Is this a positive development or a build-up to, and support of, Disclosure that will mean the undoing of humanity?

It is very much the case that this is not only sinister but powerful in its reach, as you can judge from the reactions of your compatriots. If you think about this carefully, you will realize that all of the information coming through corrupted channelers is attractive and palatable on its face, so it is only when you look at what might be missing and why those holes in the message exist, that you can put together the true dimension of what is behind the message and what the broader meaning might be in terms of human progress or annihilation altogether. It is all well and good to state the reality of evil in your midst, but then to not have truly a robust solution but more encouragement you can do it yourself, that all it takes is adopting the right attitude and holding the knowledge, will not carry you very far if that knowledge itself is corrupted and insufficient in scope to offer real answers, actions you can take, and who can best assist you in taking on the darkness. When it is acting through such powerful forces as the dark spirit realm and an alliance of physical extraterrestrials with billions of years in making advanced progress technologically, enabling them to run rings around you literally, and with all they can manipulate and control, you cannot stand up to them, you can only work around them through divine partnership. It is that simple, and hence the danger of this message and what it is trying to do.
