What rubbish are you spouting?
First, Buddhism and Taoism are 500 years older than Christianity. Hinduism is at least 4,000 years old, probably older. If anything, Christianity has been influenced by Buddhism and the great Eastern traditions, as Bertrand Russell alluded to.
Second, conditions in mediaeval Christian Europe for 1,500 years were lot more totalitarian and intolerant of liberty and freedom of thought. Ask Gallileo and Copernicus and Marco Polo. Compare the glorious reigns of the Tang and Sung dynasties with the Crusades and witch-hunts and Inquisitions. Talk about rigid social structure – were you there to witness the barbarism 1,000 years ago when the Angles were fighting the Saxons? Life under Roman rule?
Third, Western concepts of liberty and freedom came not because of, but despite Christianity. (I've left out the shamanistic religion of Judaism since it's ironic to talk about Jewish values when the Jews have been the most persecuted group in Europe in the past 2,000 years.) The factors that led to modern-day Western democracy were the Scientific Enlightenment and Industrial Revolution, the establishment of a secular state and separation of Church from State, and the revolution of the hoi polloi.
Liberté, egalité, fraternité – heard of it? That didn't come from the Bible. If the Christian clergy could have their way, Europe would be more primitive than Asia today.
