Brother I am not a follower/fan of Tahirul Qadri but lets remember these hadiths before we start labelling people.
I have just posted this on the Rumi thread and pasted it ehre as well;

HADITH: Hazrat Anas bin Malik relates that the Holy Prophet (s) said:
Three (3) things form the foundation of al-Islam1) Whosoever says 'La ilaha Illallah, Muhammadar-Rasulullah,' do not take him out of Islam because he committed a sin. .... [Sahih of Abu Dawud]

Abdullah Ibn Mas'ud (Radhi Allahu Anhu) conveyed that the Prophet (s) said, "Cursing a Muslim is corruption and fighting a Muslim is unbelief."
Narrated in Sahih al-Bukhari no: 6044, 7076 and Sahih Muslim 1:122.

Thabit ibn al-Dahak said that the Prophet (s) said, "Whoever says that a believer is an unbeliever, it is the same as if he had killed him."

Abu Huraira and Abdullah Ibn `Umar (r) related that the Prophet (s) said, "If any man says to his brother `O unbeliever' it is the same as if he had killed him."

Abdullah Ibn `Umar related that the Prophet (s) said, "Don't say that people who proclaim `La ilaha ill-Allah' are unbelievers, even if they commit a sin, because the one who calls those who worship no God except Allah unbelievers, is himself an unbeliever."

yes we need to abstain from backbitting BUT brother making the people aware of fitna so that they can protect themselves from that is Guiding (rahbari)..many scholars of past had written complete treatise on condemning person who spread fitna & lured the common masses towards it. Rahbari & gheebat are two different things altogether (yes of course intention are judged by ALLAH)
