In The Name of Allaah, The Most Merciful, The Bestower of Mercy
Imaam Ibn Rajab (rahimahullaah) said: [ أما أهل البدع والضلالة ومن تشبه بالعلماء وليس منهم فيجوز بيان جهلهم وإظهار عيوبهم تحذيرا من الاقتداء بهم -As for ahlul bidah wad-dalaalah (the people of innovation and misguidance) and those who imitate the scholars, but are not from them, then it is permissible to clarify their ignorance and manifest their dificiencies, so as to warn (others) from following them.

Imaam Abu Daawud (rahimahullaah) reported in Masaa-il Ahmad [page: 271] from Abdullaah Ibn Muhammad As-Suhaib that he said:
‘The sitters amongst the khawaarij (i.e. the Qa-adiyyah–those who instigate the fighting but do not actually participate) are the filthiest of the khawaarij.
