Muslim Puritans/extremists followers of Muhammad ibn Abd-al-Wahhab (who himself was heavily influenced by ibn taymiya) Originally funded by the British to help bring down the Ottoman Empire. This virus is predominantly found in Saudi Arabia (where it is the state religion, very different in nature to other non Wahhabi muslims), having been adapted by the Sauds in 1924 who conquered Arabia and made it he shitole it is today. Through Saudi oil money this poison is being rapidly propagated through the world, used to brainwash Muslim youth and converts alike until this Saudi cult reigns supreme. They are an extremely intolerant and violent people (towards non-beliver or 'kaffir' and to Muslims who do not adhere to there moral codes- Islamofacists if you will) with a rigid approach to religion and a disgrace to Islam. They openly disrespect the prophet (pbuh) and destroy Muslim holy sites in Saudi Arabia. They consider anything slightly pleasurable a sin and they hate bida (innovation). Not all Wahhabis support terrorism but the fact remains that all terrorists are Wahhabis or are influenced by their school of thought.
Basically a bunch of crazy mofos who have nothing to do with the salaf (pious predecessors) and belong in the stone ages and want to take everyone there with them.
When it is said to them: "Make not mischief on the earth," they say: "Why, we only Want to make peace!"
Of a surety, they are the ones who make mischief, but they realise (it) not.
"Bro did you listen to Sheikh Feiz's lecture."
"Don't listen to that crap he's a crazy Wahhabimofo"
