You aren't "anon" to the whole world. But the less information you are required to handle, the better. Never trust "but think of the children"

What's logically wrong about, "think of the children?" So we shouldn't think of the children?

if you only "think of the children" you will forget about the rest of the population. Children will be adults most of their life, it is better to prepare them for adulthood than putting everyone in an ever shrinking and taller pen

Children turn into adults that ask for social media to be regulated.
