"I say quite deliberately that the Christian religion, as organized in its churches, has been and still is the principal enemy of moral progress in the world."
Agree, but you could also say the same for Islam and Judaism. The problem is adherents are brainwashed into believing that the will of god/allah/jehovah prevails. In other words god has mapped out their lives for them and they should be gratefull for being poor, uneducated and plain stupid. Adherents are also brainwashed into believing that god, not only put their governments' in power, but they also have his blessings.
