Shaykh Rabee' bin Haadee said during the Hajj of last year (1434H) (see here)

الحجوري وأصحابه تتغلغل فيهم أفكار الخوارج

The ideas of the Kharijites have penetrated al-Hajuri and his associates.

This is a truthful word, stated upon evidence and some of it is becoming apparent. See this article for example (and an excerpt in English) to see how al-Hajuri is using the approach of the Kharijites in trying to defend and justify his takfeer of the Qabeel the son of Aadam on account of the action of murder and then trying to twist the sayings of the Scholars to exonerate himself and throw his own filth on to them - just like he tried to do with his claim that the Sahaabah participated in the murder of Uthmaan (radiyallaahu anhu).

Taking the Nasheeds of al-Qaa'idah Kharijites and Changing the Words to Revile the Ruler and Attack the Scholars of Ahl al-Sunnah

There is an audio of some of those with ghuluww (exaggeration, extremism) in Yahya al-Hajuri al-Haddadi that has surfaced in which a nasheed is recited. This nasheed maybe from at least a year ago or more and within it the reciters revile the rulers of Yemen, praise and extol al-Hajuri and also attack the Scholars of Ahl al-Sunnah in Yemen (mp3):

Someone posted the original nasheed, which belongs to al-Qa'idah Kharijites, and the first opening verses were given as a sample (the full poetry was not posted so as not to spread misguidance and allow people's emotions to be affected), so here it is (mp3):

This is proof that the fanatics of al-Hajuri took this Kharijite nasheed, devised their words and then used that to promote and express the manhaj of the Kharijites of incitations against the rulers, reviling them, and also belittling and cursing the Scholars of the Sunnah and Jamaa'ah.
