I'd buy into this. Yet that is NOT how they are used. They are used to restrict and deny facts. They are used to protect from hearing things someone finds uncomfortable whether they are true or not. They are used to create a place where only agreed upon things can be uttered again whether they are true or not.
They don't protect people. They blind them.
I agree. It is the degree to which we are aware of what we hope to accomplish through their creation. Wilful blindness is not a quality that leads to prosperity.
