Note that the requirements (you listed 5, I had it in 3) for Natural Selection do not specify a mechanism. It is enough that they happen. Darwin did not know about genes, of course.
No, that is not what I mean, here is a successful aplication of natural selection
http://anthro.palomar.edu/evolve/evolve_2.htm
A good example of natural selection was discovered among "peppered" moths living near English industrial cities. These insects have varieties that vary in wing and body coloration from light to dark. During the 19th century, sooty smoke from coal burning furnaces killed the lichen on trees and darkened the bark. When moths landed on these trees, the dark colored ones were harder to spot by birds who ate them and, subsequently, they more often lived long enough to reproduce. Over generations, the environment continued to favor darker moths. As a result, they progressively became more common. By 1895, 98% of the moths in the vicinity of English cities like Manchester were mostly black. Since the 1950's, air pollution controls have significantly reduced the amount of heavy particulate air pollutants reaching the trees. As a result, lichen has grown back, making trees lighter in color. Now, natural selection favors lighter moth varieties so they have become the most common. This trend has been well documented by field studies undertaken between 1959 and 1995 by Sir Cyril Clarke from the University of Liverpool. The same pattern of moth wing color evolutionary change in response to increased and later decreased atmospheric pollution has been carefully documented by other researchers for the countryside around Detroit, Michigan.
You see, it not only say that the explanation for the difference in the numbers of moths is because of natural selection. It explaing clearly why one type is bigger than others. It tells you the exactly cause that makes one moths die easier.
Your explanation don't say anything more than "it is because of natural selection." It really don't explain why one ideia is more popular than other, or what we can do to change the situation.

And natural selection rarely if ever takes place in response to just one environmental variable. The theory is extremely simple, but the practice is extraordinarily complex.
Or I could say it is because of newtons laws, we just have to calculate the speed and position for every atom in the earth and we wil have the same result.
But again, this explanation don't explain anything, and yet, in a materialistic point of view, it is absolutely right.

1) I have no knowledge with which to anser this. 2) It is impossible to predict how natural selection will shape future behaviors, just as we do not know whether a niche might be filled by a new bird, a mammal, a reptile...there are too many variables. But...if conditions return to, say, as they were in Russia at the end of WWII, I would not be surprised to see, as we did there, a trade in human flesh...
That is what Im saying, your explanation don't explain the problem, it is as good as nothing.

You say "In the same way that our skin protec us from infection, a healthy brain protect us from extremistc views.
The only way to get an infection is by making holes in the skin to make it suceptible to microorganism. Same thing for the brain, you can only get fragile when you are under a very stressful situation. That is the breach that an ideia needs to infect someone.
You say that a healthy brain is sucsceptible, I say that a healt brain can be damaged and became sucsceptible.". When you use the phrase "the only way", this is what I see as circularity. If we take a healthy individual (as we do in the Milgram experiments) and induce these behaviors, are you saying their healthy brains must first be damaged, and only then will they act this way? Given that the only evidence we have of "damage" is the "acting this way"....I stand by my assertion of circularity.
Let me try this analogy:
Computer=Healty mind
Internet connection=Stressful situation
Suppose that the only way to get a virus is by the internet.
Without the internet, you will never get a virus.
In the moment you connect it to the internet, it will be posible for it to get some virus. This computer now have a flaw in his security.
An antivirus software can help to protect the computer against some of the virus, but cannot protect from them all.
Ok ,"the only way" is not quite right, since an ideia can pop up inside someone's mind, but if that ideia survive without any stressful situation, I would put then in the same class as serial killers that really have a physicaly damaged brain.
Im still unconvinced that Milgram induce those behaviors.

See Atlas, above. Yes, these people continued. Yes, they thought it was real. Yes, they were perfectly healthy normal people. I really, really recommend seeing the video.
I wan't to know one thing:
Did the guy ask for it to stop? Did he beg?
Just some scream and silence won't do it for me.

That is where I would draw the line, with some pressure I could do a little more perhaps, but not much more.
In one Jackass episode, they tested some selfdefense devices and one of them was a stuntgun. They eletrocted Noxville to the point where he have to say:
-Stop, or I gonna kick your a$$!
In his most serious tone.

Of course they pressed the button one more time, after giving him some time.

Ok...I humbly suggest you read it again. The notion that I can take an ordinary man off the street and convince him to deliver powerful electric shocks to a stranger, against that stranger's will and despite that stranger's protests, then screams, then silence...well, it kinda puts me in the mind of torture. But maybe that's just me.
Shocks aint that bad, I would be more worried about the persons fellingls than about the physical pain.
Actualy I can think in something worst, there is a show in the discovery channel, that shows the cases that appears in a real emergercy room.
Sometimes, for some reason, they couldn't administrate analgesics, and they had to do something really really painfull, with the guy screaming in agony for them to stop.
Or some medic in a war zone, some years ago, were you would have to amputate a member without any pain killers, and with the guy conscious all the time.
Those cases are far more terrible than some chocks, and you would get help from people on the street to perform some of those barbaric acts.
And the medics who would see this almost every day would not become a torturer.
