Ideas originate in people. And people have names and faces in real life.
Internet names (anonymous) and the absence of faces and the impersonal dialogue still doesn’t cover up the fact that behind that curtain is a person and it’s persons who have ideas. Ideas aren’t like light bulbs suspended in the air.
Internet can provide incredible good, but there’s no denying that it can also become a haven for some who are psychologically impaired and/or who conveniently put away the restraint they would use in real life, in real places, with real people.
Everyone can put aside some of their restrait and that is the whole point.
