Are American and European muslims more liberal?

[Khairan]

when something occurs outside the scope of the sunnah there is no confirmation of it's validity...

And herein is the problem with the Sunni/Shia divide. The Shias have ahadith which support all of their beliefs, just as the sunnis do. In this regard, Ibn is wrong. Shia beliefs DO have historical basis in the oral traditions. It just happens that sunnis don't accept the shia body of tradition, and the shia don't accept the sunni body.
