"...I have been around children my entire life and while I have known some to be above average intelligent; I can't say I've encountered one at 11 to even care about these issues. .."

At age 11 I did an evaluation of religions and became an agnostic/borderline atheist.  Just came back from Taiwan, and one of my friends there has a 7 year old girl who understands the difference between their government, China's, and the political situation today.  Kids learn what they're exposed to, even sooner than age 11.  Maybe you just didn't have those talks with your children, which is no fault of theirs'.
