@angel: wikiislam and islam factory are anti islamic websites promoting Bid'aats and confusion among islam, cleverly disguised in the cover of 'teaching islam'. Check their other articles to see the level of islamophobic venom they are spitting and the sectoral divide together with twisted concepts they are promoting in islam.
As far as shia/sunni is concerned, there is no divide among islam. No shia/sunni/sufi/wahabi/whatever. Only islam.
