Who Are The Hollow?

Who are the hollow?
I would think those of adopted substance.
You know...
The ones of 'hand-me-down-ideals'.
Whatever appeals to the masses?

Those who are against anything,
They can not understand.
Especially if it requires independent thinking.
And thoughts left unaccompanied in their heads,
Poses a threat?

I would imagine them to be quite upset,
By the flow of communication.
And bewildered as to how that is done!
