There's a very simple solution to this. Stop being full of yourself. I don't mean this as an insult, I used to be the same way (although I have traditionally sided more with religion). You only think the way you do because you have the same faith in science that others have in their own beliefs. Science is only as infallible as the men behind it. New developments constantly change what was previous thought a certainty and many people choose to treat theories as if they are proven fact.
Furthermore, consider the idea that you may one day be proven wrong (factually) about one of your beliefs (particularly one important to you). Would you so easily accept this outcome and choose to live accordingly? I'm not saying this should change anything, merely pointing out that the issue is likely not a matter of right or wrong at all, but rather what one wishes to believe (which is made easier if you claim that you are right). You would be better off questioning why someone may continue to choose ignorance rather than assuming you have the intellectual advantage.
I do agree with you partially on one point though. That is the idea of living in a world that is fashioned by those contrary to your own views. This is something I have often reflectd on, even going so far as to consider the idea of building a community where I could be surrounded by like-minded individuals. Personally, I feel borders should be drawn between ideologies, not on land or resources. This way people would not be forced to condone views that they are deeply opposed to. This may actually key you in on why people would so readily oppose you on matters that seem obvious, especially in the area of religion. in many ways Christianity is a dieing religion. What were once prominate beliefs among nearly everyone are now only seen in a vocal minority (this may not seem the case in America but it is very much the case across most of Europe and the world as a whole). The few who are left holding onto these beliefs are watching the world progress away from those beliefs and likely very fearful of what their place will be in such a future, particularly since many harbor hostility toward religion associating it with ignorance/oppression/bigotry. it is likely the case that many would continue to live by Christian ideals with or without God. God is simply what grants them the authority to label their way of life as "right", just as science is what you use to deem your own views "right".
How do you breathe again?
