Isis was an extreme example, I agree. There are more common ones though. Would you prefer to leave your kid unattended on Youtube or supervised online by a random adult chosen from anywhere in the world? Most of those random adults will include people from countries where attitudes to violence are different. Most of them will have some weird religious belief that will involve involve threats of violence against the child for breaking the arbitrary rules of the religion. Most of them will be homophobic and most of them will be racist. Many of them will support killing members of their enemy groups such as the neighboring country, other religion, other race, criminals, etc. Some will encourage the kid to kill insect pests while others will punish them for doing that. Many of them won't have the patience to talk to the child, which is important for their intellectual development but boring for adults. Many of them will just be bad at caring for children.
