Just what do you think "those who actually know" know? There is N O T H I N G about the BF that the government can tell anyone who has had actual experiences with them: N O T H I N G. The ONLY thing that the government knows that we only have hints of is the extent of its own malfeasance.
THAT is what is being hidden from us: the corruption, the double-dealing, and the cow-towing to moneyed interests (and other interests, too; but for convenience, we'll leave it there for now). And sure, what's also being hidden are the stupid, ugly "experiments" on the poor bodies of whichever BF have sadly been caught in the traps of these human monsters. And all this under the guise of "protecting" the public.
Can you not see that anyone (and I'm not including you in this; I'm talking about hypothetical "officials") who alleges to be slowing the release of information for OUR benefit is only protecting their own hineys???? They are serving themselves -- not you. (And I'm not talking about low-level officials here; like SWWASAS says, compartmentalization is a real thing, AND some people have the misguided belief they are "helping". I'm talking about those at the very top, who know full well whose interests are really at stake.)
This is not about entitlement, unless by entitlement, you mean, the right to be treated like the fully empowered, sovereign, awake (or awakening) being that you are. We have the right to be treated that way, and we are not being treated that way.
The fact that we are not being treated that way, however, does not mean that we necessarily have the "right" to foment rebellion and chaos. Progress does not have to happen that way. All you have to do is tell the world what you think about things. You have to be brave enough to stand by your own truth. That's all it takes. JC didn't shoot anyone; Ghandi didn't shoot anyone; MLK didn't shoot anyone. They just spoke their truth; and all the rest of us saw -- and felt deeply -- the truth of their words, and began the work of turning the ship around.
And it has been turning around -- so you're completely right, in a way. We've all witnessed the "slow and gradual" process of getting up to speed on this "phenomenon". There are TV shows about it, for heaven's sake!!! Many of them!!! Not just one! The favorite joke of a while back was, "Polls show that there are more people who believe in BF than in [fill in your own political movement/whatever here]." There are LOTS of people who know the BF exist. There are even lots of people who know they are being actively lied to.
So it's all good. It will all be fine. Just don't sell yourself (or anyone else) short.
