I saw a video not too long ago of a kid telling his mom and dad he didn't believe in god. She yelled at him and told him he's not getting any christmas presents. Then she told him something to the likes of "that's it, we're going to church every sunday from now on". It would have been very funny if it wasn't so pathetic and real. So basically, if the type of environment you're in is similar to what that poor kid had to deal with, I understand why you'd be hesitant to tell anyone, at least publicly. But that kid was about 14 years of age and still completely dependent on his moronic parents. If you're old enough to be independent (or join the military), then you shouldn't worry about public disapproval. Just my 2 cents.
