The Mu'tazilah NGO has been set up to change the world once and for all along rational and humanist lines. For more information see the formal manifesto.
The following documents are in support of that overall aim:
Power-point presentation on Humanism
Why Atheists should be Agnostic
There is also a public forum available.
Note that the name of the NGO is taken from an extinct sect of Islam that had an emphasis on science. This name was originally provided by an Iraqi Sunni Muslim by the name of Ali Fadhil.
