I agree with you, and I think it's sad that things like this happens. However, I think that the source of the problems you're describing is more cultural than religious. The United States were founded on the values of individual freedom and self-determination above all else, and I think that makes for a very selfish culture. I also think that most "religious" people in the United States (and in other countries too) are mostly doing it to look good to others and don't actually listen to the real message there.
Another issue is that the Bible is quite thick, and it's very easy to forget that it's actually a collection of many different texts with very different importance, authors, meanings and context, and mistaking it with a coherent book to be taken to the letter. The tone of the Old Testament is very different from the New Testament, and people often forget that they were written at very different epochs, for very different audiences.
