"They Might Whine, But You've Got To Be Firm!"
For one thing, most of your interlocutors are in the wrong conversational mode or lack the professional qualifications to tell you that you're raising your children wrong. What the hell is an reporter in the middle of a call-in segment supposed to say? "Hmm, Mrs. Krabopple of Wisconsin, I can't say that I approve of spanking your children for that mild a retort! Therefore, what you have to say about the Iranian hostage issue should be ignored.----Next caller?" No, they'll be polite to your face about your private life, and you should respect that restraint by not making your private life into foreign policy arguments.
For another thing, nation-states aren't remotely like children, and people living in these foreign nation-states resent being compared to children. There's a long and disgusting history of that sort of thing. Since the US is so powerful, people in other countries do watch our media and read our blogs and whatnot. When you play parent to the world, these foreign watchers aren't thinking "oh, that's so paternalistic---but in a good way!" At best, they're worried that our country is going to blunder flat-footed all over yet another delicate situation, like some overeager St. Bernard. That's probably too optimistic a projection, though. It's more likely that most foreigners see us as both incompetant and malicious.
