Oh, please. Charles Darwin is regarded as the father of modern biology, but biologists don't worship him any more than, say, chemists worship John Dalton or Antoine LaVoisier, or physicists worship Issac Newton or Albert Einstein. Claims that Darwin was a racist do not hold water. Though some Darwins chauvinistic Victorian attitudes may seem quaint by today's standards, he was not a racist by any stretch of the imagination. Like most British, he strongly opposed slavery and supported of the Union against the Confederacy in the American War Between the States.
I've been reading Darwin's own words, and the words of those who influenced him, and whom he influenced.
Try it yourself sometime. You might be surprised that your hero isn't such a hero after all.
