Here's a word for you zerocold...
crap
Use some critical thinking. Don't confuse yourself with non sequiturs.
Military secrets are only kept a short time at best and they don't stay secret.
Further, it is usually only technical details that are jealously guarded, not the facts themselves. Example: the whole world knew about the MiG Foxbat. It was its capabilities and specs that were kept secret... for a little while.

And here's a question - if deep space stellar noise has (for a very brief time) been mistaken for alien broadcasts, how is it that you know about it? Surely such things would have been kept secret, according to your philosophy.

Sure NASA receives government funding. The state pays welfare cheques and food stamps, too. Does that buy the unwavering loyalty of the recipients?

I don't even understand your last paragraph but you appear to be spouting the same old nonsense about society not being able to cope with the stress of finding out we are not alone. Rubbish.
I, for one, would welcome it because it would help put paid to nearly every crappy intolerent religion on the planet and finally make all those "man is the pinnacle of creation" fruitcakes shut the hell up.
