I get the gist of what you're saying but I am not sure why you're so angry at the fact that this visitation did not take place. Are you saying that we are suffering because we just want out with it and basically justify what we have known all along, so as to silence those who ridiculed us?
As far as D. Wilcock is concerned, I understand his viewpoint in respect to the question of free will. If it happened en mass, 'they' would be transgressing that universal law and that is why it did not take place.
I also dont believe ET's will descend on us in 2012, the dimensional shift is about us and our transformation and not some doomsday/independance day scenario.
Peace out
