In his first speech after arriving in the UK, the pope said:
As we reflect on the sobering lessons of the atheist extremism of the twentieth century, let us never forget how the exclusion of God, religion and virtue from public life leads ultimately to a truncated vision of man and of society and thus to a “reductive vision of the person and his destiny”
What about the sobering lessons of the religious extremism of pretty much any century. He seems to have conveniently forgotten those.
And what is he even talking about in the first place? Atheist extremism? Is there even such a thing as an atheist fundamentalist group anywhere in the world?
