I'd tend to agree with you. There are a number of things I enjoy reading or writing or playing video games about that I wouldn't dream of doing in real life. Skydiving, for instance.
But there are certain hot-button topics where you just don't want to take chances. Where even if you only screw up one time out of a thousand, it costs innocent lives. Ask the Secret Service how seriously they take even "obvious" jokes about threatening the President or his family, for instance.
Right or wrong, perceived threats to children are one of those hot buttons. (In fact, you could argue that, from an evolutionary standpoint, it's vital to overreact to threats to children.) There's a reason "won't somebody think of the children?" is such a cliché, and that's because it's true.
