I have lived more than enough time as his age mentioned in US and I have never encountered such questions or remarks.
I do not think people are so dumb here. They are curious to know about your culture and traditions but not so stupid to ask me if I was brought up in a "no tubelight" home or in a forest or such thing.
Now a days I have heard that kids and their mothers are making up stories to get into limelight. One kid wrote a letter to TV station and lied about her father to collect free ticket to a show. Mom and kid got caught in an interview for the lie and then mom publicly apologized for the behavior.
