Isn’t it ironic that those who espouse to Darwinian evolution are also the least likely to have multiple children and most likely to support and/or obtain abortions. They are supposed to believe in survival of the fittest. Only those who reproduce stand a chance at survival, and those who reproduce the most stand the greatest chance for survival and subsequent evolution. Apparently Darwinian liberals are not fit to survive!
In all seriousness, I think this reveals the cognitive dissonance of liberals. They cannot consistently live out their worldview. In fact, given the maxim that people behave in accordance with their beliefs, I tend to think most adherents of Darwinism do not really believe it. They may give intellectual assent to it, but they don’t live it. All that matters is that God is out of the picture.
