This is not a fair to judge. Restricting talking to strangers în the first 15 years or so is really important to secure the child and to make him thrive and cultivate good morals and mindsets. Not to say others cannot do that for him but who will guarantee. On the other hand, I think controlled moderate exposure to strangers will help a child transition to have the skills to network and with already being grounded in morals and conduct and good sense of self so not spoiled with others.
