I have a couple of thoughts that will probably draw fire from both sides, but here goes. I'm not trying to be controversial or throw a punch, so please, I beg you, don't just "react" to what I have to say, but do feel free to criticize if you can.
First, the whole stem-cell thing. I think it is both inaccurate and an injustice to say that only religious people, in this case Christians, are uncomfortable with the idea of stem cells. I agree that the promise they hold for medical science is potentially incomprehensible: but then, the same was said (and true) for many of the human experiments conducted by the Nazis upon Jews. (Speaking of Jews, the dude who wrote about Christians not even believing the Bible because they don't slaughter animals: you should read a little more closely -- Christians aren't supposed to sacrifice animals). Anyway, there are LOTS of people who protest it because they are simply uncomfortable with the idea of creating a life, much less a human life, for the purpose of destroying it. Perhaps destruction is not the word we use, we merely "arrest development..."
Second, the number of Christians in the USA. I think I can probably speak to this more accurately than anyone in this forum. In college, I participated in a first-ever political study with a professor in which we created a survey research "measurement" of "religious affiliation." This was a coefficient weighting assigned to an individual survey respondent based upon a number of questions that were correlated to demonstrate an overall strength of religious commitment. In other words, beyond nominally asking people to identify themselves as Protestant, Catholic, or Non-denominational, or Other, we asked them to quantify their church attendance, to quantify the amount of time per week they spent in non-church-service religious activity, to describe their religious heritage (ie, is their current faith different from that of their parents or grandparents), and other more accurate questions regarding their religious commitment (the survey, without going into detail, was not religiously administered -- the questions were added to a nationally conducted survey on political topics and conducted by the Pew Center for Political Research; the questions were part of the demographic information section, and thus could also be correlated to economic and other demo data, as well as to the political affiliation data). We found that few people in this country actually qualify as devout Christians (less than 20 percent). A larger chunk, as would be expected, were marginally committed (church twice a month, that kind of thing). I leave it to your interpretations as to whether that is good or bad, but please let it inform your opinion of "Christians in the country control/force/oppress X." That kind of generalization just doesn't stand up to the data. It may be your experience that some Christians you know "control/force/oppress X," but that is VERY different from the former, generalized assertion and constitutes a bigoted, prejudiced attitude. Aside: Interestingly, far more of the middle-ground Christians claimed Democratic Party membership than Republican.
Third, Creationism. It seems to me that everybody talking about this topic thus far is victim of a very popular false-dilemma argument. Creation OR Evolution is not the dichotomy. Naturalism vs Creationism is the real issue. Evolution is merely a scientifically measurably mechanism and not a theory of origin, and it can just as easily be incorporated as a mechanisms into either Original school of thought. There are many of us Christians, myself passionately included, who are unable to deny the scientific evidence and conclude not only that evolution is real, but also that the Universe is extremely old. (Any Christian who believes Romans 1:20 should also realize that its correlatives are true, and then take a good long look at the fossil record -- PM me if you want to know what I mean.) Evolution eventually brings one back to the first organism, the first RNA, the first protein, the first amino acid, the first organic molecule... ad infinitum to the First Thing. And I do mean the first "Thing," big-T, the first anything. For a naturalist, it starts at the Big Bang. But, even Steven Hawking is uncomfortable with current Naturalist theories of origin, because they leave too big of a door open on the other side of BOOM, where darkness and mystery still reign. An old-earth Christian (as we call ourselves) also considers the big bang a legitimate event, but it is not the First Thing. God remains the First Thing. Let me say that not buying "Creationism" as it is popularly packaged is not a good reason to discount Christianity. Its not a compromise to put Genesis into context, understand the intent of the author, and to conclude that there didn't necessarily have to be a literal 7-day creation event and a literal couple called Adam and Eve in order for God to have created the Universe. Nor is it a compromise to suggest that humanity is still special in God's sight, as he indicates that it is, despite our descent from less evolved organisms. Nor is it a compromise to say that I am even MORE awed by God's grace, because out of all the conceivable worlds in the Universe, and out of all of the conceivable races, the Mighty Creator of All reached across the vastness of unfathomable time and infinite space, and became a man like me. Frankly, an insistence on a young earth, a 7-day creation, and a literal interpretation of Genesis sullies the deal for everyone involved.
Fourthly, venom. There is a lot of it being spewed in here. We're human and prone to rage, so that's all well and good. But be sure to ask yourselves why you are really so angry, those on either side. Not the ready reason that is easy to give to strangers on a forum. The tough answer, the deep, unresolved conflict that you can't quite enunciate but neither can you ignore. Is it because for the other to be right is for you to be wrong, and you are simply uncomfortable with the implications? Is it because the arguments the other makes are too close to your own doubts, and your shibboleths cannot take another assault without your world falling apart? Is it because you still can't forgive that father, mother, boy, girl, teacher, Pastor, uncle, sibling, etc who stuffed their ideas down your throat and caused you so much personal pain that you seek them in everyone who has the same ideas, trying to patch the wound?
Lastly, I think it was Petrek that made a very relevant observation. Those of us who claim to know God really have had experiences with Him. We are deeply aware both of our own souls and of Him. Frankly, there's no point in arguing with either A) someone who has experienced God, or B) someone who hasn't and insists that you can't. Its like trying to argue with a Mexican that there's no such thing as Spanish. But I think many of you who are really curious, conscientious agnostics, and not evangelical atheists out to increase the ranks, need to ask yourselves this question: Have I ever had a really spiritual experience? Am I actually aware of my soul? Do I know its there? Start from there. If you're sure you haven't and never could, that's okay. Good luck to you and I hope your right. I'll be okay in either case. If you have, if you are certain that there is a soul in there, wanting to be expressed, then I suggest you spend a lot of time trying to hear what it has to say.
