To me, ignorance is one of the worlds largest problems.
It promotes lack of education or limited education.
Many keys to people being able to get along in peace is tied to communication. The more one is educated the possibility of being a better communicator rises dramatically.
This, though, is not like educating one about the ABCs. It's like how my former therapist put it:
I was telling him my issues and he says "there is one client that comes to his office. He hears voices and sees things that arent there. At first, these dellusions were so worse that he needed medical attention. Now," the doctor tells me, "he is going to work, has a family," and so forth "AND he still hears voices and sees things not there."
So his ignorance (mental illness or not) to what he is experiencing is real. The therapist said we don't tell them it is not. It is just it is
not a problem anymore because the client learned how to live with the voices etc that other people cant hear and see.
If specific religions around the world did not give religion of itself a bad name by all the murder the people done in the name of their religion, I think that hopefully, people wont be talking about "god of the gaps" and just accept, like the therapist, that people will "hear voices and see things that are not there" and
that is okay. No matter how they justify it, its between the person and their experience (and doctor, or their god, or whom/whatever)
Religious Politics cause so much mess in people's head that we (in some parts of the world) can't even see what other people see without needing to step in their shoes.
