Chaim I agree with you completely that if God used evolution as a method to create then that shouldn't in any way diminish our faith in God. I have accepted evolution as fact based on the evidence that I've seen. In my opinion there is simply no other reasonable conclusion that can be drawn based upon the available fossils, genetic evidence, etc.
However, I don't promote the idea anymore because for some people, it does seem to hurt their faith. For others, it becomes an excuse to "act like an animal", or makes them feel as if they are somehow not made in God's image, or makes them feel as if they are not spiritually separate from the animal kingdom. The atheists in the Church of Satan use this concept as the basis for their religion by saying that we should give in to our animal nature and not deny our flesh anything it desires. They don't believe there is anything beyond the flesh and that we are merely animals. In greater society it seems to have led to an overall devaluing of life. I've even had atheists tell me that because a human fetus is no more sentient than a full-grown pig, then there's no reason that slaughtering one should be considered immoral but not the other.
The concept of evolution has been used to cause morals to erode in society.
So that's why I no longer try to get people to accept it, even though I think as far as physical reality, it is the truth.
What's important is to realize that regardless of how our bodies were created, we are spiritually distinct and separate from the animal kingdom and as human beings we have an obligation not to give in to selfish, animal natures.
