What proof, in the case of More?
If you just
choose to believe, without evidence, that he repented of his religious oppression, that is one possible answer to how such a man could be considered a saint. But I know of no evidence that he did so.
Where have I claimed any such thing? If anything I explicitly disavowed the assertion that the anti-science actions of the church were deliberately intended as such.
Darwin did get a lot of flack, and not just from Catholics, but he had the fortune to live in a
Protestant country. And one thing the Anglicans did get right was to content themselves with presenting
arguments as to why they thought he was wrong, as opposed to threats of torture.
Newton, of course, also lived in the UK, but more to the point nothing in his scientific ideas threatened christian beliefs, as far as I know. His ‘biblical scholarship’ may well have earned him pride of place at the next barbecue under Catholic rule, but not calculus or mechanics.
Copernicus
was, according to many scholars, terrified of how his work might be received by the Church, despite being supported by clerics up to and including the Pope. This is one of the explanations given for his reluctance to publish, and would probably be the main example of how the church was, at times, explicitly anti-scientific, were it not for the far more evident Galileo affair.
The others were no threat to a Catholic dogma. You don’t get brownie points for not oppressing those who agree with you!
Try to force feed yourself the idea that that is only one explanation of the Galileo affair, and not even one that is at odds with what I actually said.
