1. People should understand the theory of evolution whether they believe in it or not, just as they should understand socialism or segregation. You neve know when something you are reading or watching will just not make sense unless you understand evolution, whether you believe it or not.
2. A parable does not mean anything until it is interpreted, so how can you take it literally. There are people who seriously try to take at least part of the Bible literally. They have found hundreds of God's commandments, and try to live up to them all. They are the Orthodox Jews. The only Person who knows what the Bible means without interpretation is God. Being finite and corrupt, we are not capable of this knowledge. All our Bible knowledge is interpretation. One of the Devil's favorite tricks is to convince two groups with differing interpretations that their group takes the Bible literally and the other group doesnt, and then sit back while they start killing each other. It worked great in Yugoslavia.
3. Under a strict interpretation of the Constitution, corporations would not be persons with the same rights as real persons. Whatever rights they had would not be inalienable but rather granted by us humans through legislation.
4. Being anti-abortion and wanting abortions to be illegal are two different things. Prohibition did not stop drinking, but it did make it difficult to promote responsible use of alcohol. As long as women can leave the country, making abortion illegal will not stop abortions. And it is not the most effective way to reduce the number of abortions to a minimum. So you can make it illegal, or you can make it happen less often, but not both.
5. Abstinance from getting pregnant and abstinace from sex are two different things. Experience shows that teaching abstinance from sex gets you a lot of pregnancies, wheras teaching how to engage in sexual activities responsibly (without getting pregnant) does reduce pregnancies (and also abortions). Does God want us to affirm strict rules that dont have good results in practice, or does He want us to produce the best results in a loving manner?
6. People used to feel that interracial marriages were unnatural and defiled the institution of marriage, and somehow diminished or dirtied their own marriages. They felt that way very strongly, but they never could explain it, because they were wrong. Gay marriage is the same sort of thing and produces the same strong reactions.
7. Some people think God condemns anyone born too early or in the wrong part of the world (anywhere where it is in fact impossible to hear about the Gospel) to hell. Since this is obviously unfair from any human understanding of fairness, we obviously have no idea what God's fairness (real fairness) is. It could involve slavery, oppression of one group by another, insider trading, etc.
8. An all-powerful God can save anyone He pleases. We should pray to Him to adopt a way of selecting people for salvation that does not automatically rule out anyone who has not heard the Gospel. Instead we pray to Him and praise Him for saving Christians. In God's eyes this is selfishness and will not go unpunished.
In response to 2, I said 'One of the Devil's favorite tricks is to convince two groups with differing interpretations that their group takes the Bible literally and the other group doesnt, and then sit back while they start killing each other. ' Our Founding Fathers and their ancestors had just escaped from exactly that sort of thing. That is why they founded an officially secular country. And God loves this simple and elegant solution which wards off the Devil's mischief. Proof is that He has blessed this officially secular country with a vibrant religious life that is unmatched in any country that is officially Christian. He does not want us to mess with our solution.
