Why do you care?

[Xavier]

Christians burnt fucking hundreds of scientific minds at the stakes! Or did you forget that little piece of history? Spanish inquisition? Surely you are aware of these events? You lot held us back. You burnt the intelligent. The only reason we can advance so quickly now is because you can't touch us anymore.

This.
The Christian church also destroyed much of the learning and knowledge from the Greco-Roman world because it didn't fit in with Christian teaching.

It wasn't till the Renaissance that many classical texts were redicovered from the East.

For virtually a millennium scientific progress went nowhere and Christianity is largely responsible for that.
