Politics and Religion.... any other controversial topics for today?

So I'm a little disillusioned with both politics and religion and realizing that I'm pretty agnostic about a large majority of both these areas. There's such a large area of these that we can't ever know and things we will just flat out never understand over the course of our lifetimes. We are so sure we know what we know, but what about the rest of the world? Sure, you're a semi "expert" on Christianity, but what about the rest of the world religions? People that are born Buddhist stay Buddhist, people born Christian tend to retain their values and beliefs, and if I had been born in this area of the world I would 95% live and die a Muslim. What constitutes religion? How do we know we hold truth when the rest of the world claims to as well? All of this can be said about politics too. Does the average American have any idea what is going on in the Middle East today, or in the last thousand years? Why don't average Egyptians concern themselves with China's gross abuses of human rights? We are all so wrapped up in our own regions and interests that little attention is paid to terrible situations occurring all over the world. How can we claim to know what US foreign policy should be? How can Candice Mercer in 10th grade claim to have any total grasp on why America invaded Iraq? We speak with such small knowledge of amazing intricate and complicated issues involving social orders, different religions, different world views, different conceptions of life and peace and truth. Do we even have any idea of how our own religion of Christianity has been shaped by politics? Why did Augustine's view of human nature win out over Pelagius? Was it actually based on moral truth or just political interests? I think we would be shocked at how many of the things that we believe and take for granted were actually largely politically determined. Who are we to say we have any grasp of who Mahmoud Ahmadinejad is and what his interests are in Iran? We would need to know the political history of Iran, the concept of Shiite Islam and how it functions in contrast to the government and how ironic it is that there is any sort of Shiite government anyhow, what the Iranian relationship is with Syria, historical and current, and an immensely cast number of other aspects. Oh the immense amount of pride and simplification that happens all the time! In both America and the rest of the world, although arguably more in United States.
I have to run, so I'll finish this thought process later I suppose.
