I dont know what deoband group you're talking about, maybe you can elaborate, but for me these are external ideologies which have 'sided' with taliban, and are defaming their name.
Because not everyone in the taliban is an angel, or even within pakistan in OTHER organizations.
But other then that, my post that i referred to you had the my views on foreign personnel within taliban.
Crescent I am talking about deobandi organizations that have adjoined with Taliban, such as Sipah-e-Sahaba, and Lashkar-e-Jhangvi. Are these organisations also "defaming talibans' name"?
