I find it to be a problem that you equate what the Taliban did with what the Nato forces did.
No we are not perfect and some of our troops have been VERY wrong---it is unfortunate, but mental illness and cruelty shows up there as well on the streets of Aurora and Newtown.
I am stopping my typing now, before I violate the politeness policy
Not that I am sticking up for the Taliban, because I am definitely not, but here is a potted history from your Wiki link about their beginnings.
Meanwhile southern Afghanistan was neither under the control of foreign-backed militias nor the government in Kabul, but was ruled by local leaders such as Gul Agha Sherzai and their militias. In 1991, the Taliban (a movement originating from Jamiat Ulema-e-Islam-run religious schools for Afghan refugees in Pakistan) also developed in Afghanistan as a politico-religious force.[46] Mullah Omar started his movement with fewer than 50 armed madrassah students in his hometown of Kandahar.[46] The most often-repeated story and the Taliban's own story of how Mullah Omar first mobilized his followers is that in the spring of 1994, neighbors in Singesar told him that the local governor had abducted two teenage girls, shaved their heads, and taken them to a camp where they were raped. 30 Taliban (with only 16 rifles) freed the girls, and hanged the governor from the barrel of a tank. Later that year, two militia commanders killed civilians while fighting for the right to sodomize a young boy. The Taliban freed him.[46][47]
