This thread is *so* going to get closed.
But while I can...
I think that the article has a lot of truths, but goes a bit overboard with the idea of a belief being like an infection.
What fantasy world you create stems directly from what kind of reality you experience. Had Germany been a better place to live while little Adolf was growing up, he may never have turned into the maniac he did. If Mr. Bin Laden didn't see the evidence of the Great Satan every day, he may never have cause to hate us. Heck, a study of mythology and religious philosophy can show us that the way in which one grew up heavily focused the everyday fantasy you lived out. The Aztec were certainly living out a different fantasy than Napoleon, and both were products of the world they existed in at the time.
It's not a good thing to consider anybody evil just because they have a destructive fantasy. There is a reason for that fantasy -- remove the reason, and you can remove the destructive fantasy. At the same time, you do have to realize that this is perfectly rational for them. You may never be able to argue them out of it, but you may be able to put yourself in their shoes at least somewhat and see how, maybe, it would be possible to think slightly like how they do given their circumstances and ideas.
Nobody is infected with an incurable, virulent evil that you can simply ethnocidally eradicate. If you push back on people who are already at the brink, they just push back harder and harder until they can't push back anymore. Compare it to a virus: you counteract it, push it to the brink of extinction, and those that survive come back 30 times stronger and immune to your old methods. It's a kind of evolution, a natural selection for ideas.
We can't destroy any ideas, nor would I support anybody who would want to -- even so-called "evil" and "destructive" ideas are useful for understanding how they can arise so we can curtail them.
I agree a lot with what the article is saying in a lot of respects. But I can't stomach the thought of any way of looking at the world as a cancer that can be eradicated. Because if holy wars over the years have taught us one thing it is that ideas never die...they merely become less harmful.
