Well, there certainly are a lot of Christians, Atheists, and Agnostics here... All very interesting. Now why don't I offer some opinion from a different religious perspective:
I'm always hesitant to consider myself a religious person--because on one hand, I firmly adhere to a religion, but on the other, when most people say "religious" they imply "Christian", which I'm not. Instead I am Pagan--meaning, in a nutshell, that the higher power I believe in is the spiritual aspect of nature herself (I say herself because of the depiction of the Earth as our mother). I picked that religion partly because my mother practised it for a while, and partly because I liked its interplay with magic.
That leads to one of my points: the kind of faith (or lack thereof) one chooses to believe in comes from one's characteristics and experience. Once chosen, it feels right and makes sense. Even so, everyone has their own unique opinion of what they believe in--whether consciously or subconsciously, people make their religion (or atheism/agnosticism) their own. They interpret it in a way that makes the most sense to them.
There aren't really any pagan churches, but the church I went to held one belief that I really admired: the notion that all religions and belief systems point to fundamentally the same thing. Even atheists believe in the betterment of the self--just without any notion of a higher power. That betterment of the self is one common aspect of all religions, along with a sense of connectedness. An atheist might experience the latter through a sense of community--i.e. being around friends, or even realising that all people have such mundane things in common as being human and having life. Each religion expresses such fundamental beliefs (which seem simply rooted in human nature) in its own unique way--different nuances of the same thing.
I think that religious conflict arises from either the failure to realise the above, or someone's notion that some specific practice of some religion is causing harm to people (which may or may not be true). Either way, those things are misunderstandings, just like the misunderstandings we may have about certain other people. Though the misunderstandings between religions are nigh impossible to remove, they can be mitigated by bringing their fundamental practices and beliefs into the light. For many times we fear what we do not know.
(Paganism, for example, has quite a history with such misunderstandings, due to it being labeled as devil worship and such. Even today many people frown upon Wicca, a section of paganism, for its practice of casting spells, but mostly that's because they don't realise that Wicca advises against controlling or harming others with such spells, not to mention its fundamental vow to "let it harm none".)
I believe that the religions that are out there are meant to be used as guidelines, rather than strict doctrines. They are meant to be systems of beliefs and practices that one can choose to adopt. The person might also choose to be eclectic, borrowing ideas from several different religions, and/or deciding on their own beliefs and perceptions on how the world works. But once you have a belief system that you can really relate to, it gives you the potential to start to make your life more meaningful. This even applies to atheists--I can bet that any atheist can find some philosophy or principle of life that they believe in, and if that works for them, that's perfectly okay.
Even I don't hold on to my religion that strictly. Though my beliefs are rooted in paganism, I consider myself eclectic, borrowing deities and principles from other religions if they have a significant meaning to me. Because my religion is not very common, I often find myself explaining things about it to my friends, but I try not to impose my beliefs on them. For me it's kind of awkward to try to explain religion to an atheist, but hey, if they're curious about my beliefs, I might as well explain them, and if they don't believe me, then it's just not their cup of tea, and that's okay.
