Look up what Darwin had to say about race. The leftists ignore it and focus on Darwin vs. religion.
One of the revelations in the “Dark Side of Darwin” was that he was a fierce racist,
and used his theory to justify and support that racism.
Also, the main reason that he came up with his theory was to replace or “kill” God. It is no accident that when communists take over a country, they do not teach the people the benefits of communism, they teach them evolutionary theory and atheism. Then all you have left as your “higher power” is The State.
Until then I shall continue to hold his ideas in the “close but not cigar” category.
