I notice the same thing about today's Sufis. They have nothing to offer...only criticism of Salafi and "Wahhaabis"....that too based on ignorance. What they don't realize is by constantly attacking and demonizing the Muslims who adhere to the Sunnah, these Sufis are resembling lthe Jews in the time of Eesa ibn Maryam Why did the Jewish scholars and rabbis consistently oppose the Prophets? Because while they knew these Prophets were upon the truth, they were afraid of losing their power and influence over the masses. This is the same thing with Sufis, they fear Salafiyyah because they fear the hold they will lose over the people whom they are leading astray.
