A good historian doesn't accept assumptions as firm conclusions without investigating. We have evidence of several motives, so we can pretty much rule out your single-motive model, at least until we see some evidence.
Motives for what? What on earth are you on about?
Are you now going to attempt to show that
all scientists who accept evolution, which is the vast majority, have been duped by an evil conspiracy, and that all the evidence they accept is lies and hoaxes? Please, offer some proof for this. I'd be really interested to see it.
If evolution is an evil conspiracy which does not explain the facts, then how else do you explain:
-- the sorting of the fossil record
-- variation among species, increasing over time
-- genetics showing that most animals share a large proportion of the same genes
We'll keep the list at 3 to simplify things.
This has got nothing to do with racism or eugenics. It's looking at how well the theory fits the facts. If you are unable to give satisfactory alternative explanations for the above, then you cannot substantiate your claim that evolution is nothing but an evil conspiracy.
It would be helpful if you could find evidence of a scientist who was committed to the theory of creation, and rejected it on the basis of evidence.
You can find stories today about scientists who decided to become creationists, or creationists who decided to become scientists. I'm not sure why you seem to want me to supply some 19-century miraculous conversion story. Not being an expert on the 19th century but knowing a bit about human beings, I would hazard a guess that those who thought Genesis should be interprested literally might have felt threatened by the ToE and resisted it. Younger people, the next generation of scientists, would have have been more accepting of the idea, and so it went. It usually takes a bit of time for a theory to take a foothold, and blow old and cherished ideas away, but in the case of evolution it didn't take that long.
What's more, it is erroneous to blame Darwin for a sudden shift from creationism to naturalism and rationalism, and he was not the first to observe that living things have changed through time. This shift was taking place before he was born. You can read
here about pre-Darwinian scientific ideas about biological evolution.
Evidence-based conversion is looking more and more like an unsupportable myth.
There is a lot of evidence for evolution here on this forum. You're just choosing to close your eyes, plug your ears and scream, "I can't hear you."
What's lacking is evidence that evolution is nothing but an evil conspiracy.
