This supports my position.
I am not sure how this supports your position, both Charles Darwin and Lincoln were luke warm at best toward religion, and distanced themselves from traditional religious beliefs

Darwin and the insufficiency of sound bites
There is no simple answer to questions about Darwin’s religious sympathies. This is partly because they changed over time. To a first approximation, his trajectory was from the Christian orthodoxy of his Cambridge years to a non-biblical deism at the time the Origin was published to a more thoroughly agnostic position in later life. This makes a neat and ironic story, given Darwin’s initial training to become an Anglican priest and given the clerical attacks on his theory that he had to endure. But it means that what was credible for him at certain times in his life was not at others. For example, the sensitivity with which in the early 1830s he responded to the sublime beauty of the Brazilian rain forest, and which he said had been associated with his belief in God, faded in old age. In 1859, at the age of fifty, he could still believe that the laws governing the evolution and diversification of life had their origin in a Creator.
A second reason why Darwin is difficult to pin down concerns the fluctuation of belief. In private correspondence he admitted that his beliefs often fluctuated, even within his most agnostic phases. There were times when, in his own words, he supposed he deserved to be called a theist. At other times the strength of his belief in an ultimate Creator waned. He did, however, insist that he had never been an atheist in the sense of denying the existence of God – a point sometimes overlooked by his fundamentalist critics and his atheistic champions."
The prevalent view among Christians at the time of Charles Darwin was that whites and blacks were not created equal.
Abraham Lincoln was faced with the same world view of Christianity, even though he was closer to secular Deism than Theism in his life.
