In order to defeat ISIL, we must inoculate all the people from becoming radicalized, both here and abroad. This is the elimination of wrong memes within our traditions, our cultures, and language. We need to identify and eliminate garbage ideas.
There are still people who believe the earth is flat and the sun rotates around the earth. This will be a long haul.
The first big meme is that there is a god. This meme must be eliminated. When we create two diametrically opposed hypothesis, one saying there is a god, the other saying there is no god, the evidence all seems to indicate there is no god.
The evidence must be real, and not hear-say. That eliminates all the old "holy books", and all old religious papers. Those people who cannot be called upon to testify and be examined.
So religion must be abandoned, and logic must take over. That will change the world. Oh well.
There should be a word to describe these sorts of concepts, that have been handed down without testing. Wait, there is, myths. Yes, religions are myths, but we should keep the few truly logical lessons that come out of the stories. That is to say that which is common to most religions, or at least the "do as I say" parts and abandon the do as I do parts. Oh well, in the end we all just die anyway.
