Which deviants of the Era do they remind us?!

Shaikhul Islaam Ibn Taymiyyah (rahimahullaah) said:

”The people of bidah, such as the khawaarij—they initiate an innovation, make takfeer of the one who opposes them and declare lawful the shedding of his blood.  These (people) refute the innovation of each other, whilst he (i.e. the refuter) is also an innovator. So he refutes a bidah with another bidah and falsehood with (another) falsehood.” [Al-Majmoo 16/96]
