The Afghanis need to be protected from Islam.
and we do that how? Kill all of them? because the standart Afghanis are hardcore islamists so they definitely don´t want protection from Islam (the Taliban are just the top lunatics of all this radical madman). but as said they don´t differ that much as you might think. they believe in child marriage and treating wifes worse then cattle... this is how they (at least most of the male) whant to live.
