This is a wonderful thread! Farid, you are providing a very valuable perspective that helps us non-Muslims have a greater understanding of the background of some of the conflicts in the Muslim world.
As a Nichiren/Soka Gakkai Buddhist, I would say our beliefs are closer to Humanism, believing in the Buddha Nature/Godhead of all living beings (even the assholes). It is a matter of bringing out that aspect in order to win over the also-ever present negative parts of our lives. We also believe that, as someone else here said, the best way to "prove" the validity of a religion is by how one deals with one's own life.
There Are of course many beliefs/virtues most religions have in common. Without intending to put down anyone's belief system, one of the issues I see is that the Abrahamic religions (Judeo-Christian and Muslim) have a strong component of authoritarianism, as in "these are the rules." This served a valuable purpose in terms of establishing moral codes of behavior in pretty barbaric times. We believe it is up to us as individual humans to transform our own lives and the world for the better, by taking personal responsibility for our destiny. This definitely includes speaking out strongly for truth and justice!
We all share the destiny of living on this planet in such a turbulent, hate-filled era, and I am glad to see efforts like this thread aimed at creating more mutual understanding and appreciation of other cultures.
