May want to check yourself before you wreck yourself there - most of those German eugenicists were, in fact, Christians who were explicitly rejecting Darwin's theory of common descent and instead drawing justification from the divine separation of the races.
No doubt the church has done some amazing things, but these really great things do not wipe away century upon century of oppression.
That's a nice piece of revisionism. So it was fellow scientists who must have taken an elderly Galileo to tour the many devices of torture employed by the inquisition. It must have been fellow scientists who responded to his work with the formal statement that,
"The doctrine that the earth is neither the center of the universe nor immovable, but moves even with a daily rotation, is absurd, and both psychologically and theologically false, and at the least an error of faith."
Oh wait, that was the Church's formal declaration to which Galileo responded,
"The doctrine of the movements of the earth and the fixity of the sun is condemned on the ground that the Scriptures speak in many places of the sun moving and the earth standing still. . .I think that in the discussion of natural problems we ought to begin not with the Scriptures, but with experiments and demonstrations."
From the primary sources of the time, then, it would appear that the bolded section above was the actual issue, rather than some professional dispute among "fellow scientists" that the church sorrowfully took part in. Indeed, Galileo's recantation, he makes it absolutely clear that the dispute is one between science contradicting theology and not, as you seem to imply, one of science contradicting science.
"Because I have been enjoined, by this Holy Office, to abandon the false opinion that the Sun is the center and immovable, ...I abjure, curse, and detest the said errors and heresies...contrary to the said Holy Church."
Science is biased towards theories which consistently explain evidence and against theories which are contradicted by evidence. The fact that scientists are unimpressed by climate change skeptics and/or creationists is not a flaw in the way science works - it is due to the lack of supportive evidence for those positions and the plethora of evidence which contradict them.
Curiously, neither does making bald assertions that are unsupported by evidence.
