Scottishdiem, I look at the body of art, architecture, literature and music created in Europe since the Renaissance and see little to rival its wealth, depth and breadth in Islamic or any other culture. The Byzantine world aimed high, but much of the beauty in Istanbul is Orthodox. Moorish medicine and science provided a haven for knowledge during the Dark Ages, but stopped moving on after about 1600: curious to know why.
Come the Reformation and Europe starts to sparkle with challenges to religious thought: the free-thinking philosophers, true science, medicine, parliamentary sovereignty and modern law. I grant the malign influence of the Inquisitions and the Puritan and their repressive tendencies (the Taliban of the day) but disagree that the general trend to the Enlightenment is only as recent as the Victorians. Their public health and educational initiatives are the foundations of our contemporary social landscape. Democracy, freedom of thought, speech and assembly have been codified and extended to all in the last 150 years.
History is so huge, everybody can pick out the bits they like and object to the injustices they perceive. But it has been a progression, although it has moved in fits and starts.
As an atheist, I don't believe religious superstitions, but Judaic and Christian moral codes are (generally) civilising influences. The works of art that were commissioned and dedicated to religious belief have left a legacy that millions flock to visit from all over the world. So was much of the classical music that's loved from Beijing to Bristol and Baltimore. Shakespeare and the King James Bible resonate through the English language wherever it is spoken, and Shakespeare distils the essence of the human condition, good and evil, quicker and more truthfully than most psychologists. And if the civilisation that has been created out of this stew is better than what went before, then some of the credit should go to the great figures of the past.
Maybe "horrified" was a touch melodramatic on reflection. IMVHO, a failure to acknowledge the contribution of religion, largely Christianity, is a bit dismissive.
