This is a very unreliable way to think. The truth of something is completely unrelated to its popularity..
I'm not referring to popularity..
One has to look at the history as well.
eg. the mainstream/orthodox is not beliefs that did not exist 1500 years ago
But what you are implying is that the mainstream is right simply because it is the mainstream. That doesn't work.
The first major split in Islam, was sunni-shia. I see the division as mostly political.
i.e. fighting each other over who should be in charge (govt.)
..much like royalty vs democracy .. shia emphasise lineage of Muhammad (peace be with him)
over ability or consensus.
I do not see division, and the emergence of new sects/beliefs as a good thing .. although it is
bound to happen due to human nature.
"
We reject interpretations of Islam that call for any violence, social injustice and politicized Islam. Facing the threat of terrorism, intolerance, and social injustice in the name of Islam, we have reflected on how we can transform our communities based on three principles: peace, human rights and secular governance. "
I think education is the key here .. a broad education, which leads to a more balanced government,
whatever religion the people who make up the govt. belong to.
Oppressing others is no good, whoever is doing it.
Some nations have less access to a broad education due to poverty or cultural customs.
There is a major difference between Afghanistan and Saudi, for example .. but both countries
are majority sunni Muslim countries.
