If the history of science has taught us anything, it's that scientific truth never bows down to political opinion. Political institutions have had to concede that the Earth is not the center of the universe, that whites are not biologically superior to members of other races, and most recently, that the universe was not created by God 6,000 years ago. Eventually the evidence will pile up to the point that no rational thinking person can deny it, and those who still cling to the outdated theory will die out. It may take a long time, and momentary setbacks are to be expected, but I don't think it can realistically turn out any other way in the long run.
