Although the taliban have had their faults, we will not believe blatant lies about them for many reasons, here are a few:
1. They are muslims, muslims have alot more honour and morals than non-muslims, you said the taliban are guilty of rape - my mind cannot associate that to muslims fighting for islamic law, that accusation is better suited to non-muslim troops who are filled with lust - the figures of how many female troops act as w hores and get pregnant prove it
2. We are told in the Quran:
O you who believe! If a Faasiq (liar — evil person) comes to you with any news, verify it, lest you should harm people in ignorance, and afterwards you become regretful for what you have done [Surat Al-Ĥujurāt {49:6}]
3. Media from countries at war in afghanistan is bound to be biased towards the 'enemy', they cannot move away public support for their wars so they have to justify them by reporting the most unreliable false claims. An example of that is the recent US/NATO bombing of a wedding which was then blamed on the taliban
4. RAWA is a group that wants 'democracy' they are bound to be against islamic punishments, even against male criminals. I've noticed they do not report why certain punishments are carried out, an example is the public execution of a woman in a football stadium. They did not say that the woman had admitted to killing her husband. So I'd be wary of such groups
