We don't live in the same Europa. I live in the Europa of human rights, secular, democratic and so on. That is also an European heritage.
Liberalism, the age of reason and the Enlightenment were born out of Christianity rather than simply in opposition to it. theological debates on the individual's soul, free will and natural law paved the way for ideas of human rights. Secularism was the consequence of a debate on the division between the public material worlds governed by man and the private spiritual and mental world governed by god.
It's part of the reason why that same European civilisation opposed communism because the world they imagined without God didn't see an inherent value in human beings and believed their rights came from the state and not nature (or God). So, the two are connected.
But yeah, I would love to have seen more Roman and Greek buildings, art and architecture preserved rather than demolished by Christians. They have their place in European culture as well, particularly as many Pagan beliefs and philosophies went on to influence Christianity. If we had kept the library of Alexandra it would have been a goldmine for starters and we might have had the Renaissance a lot sooner.
