Ratzinger on "Laicism" and Religious Freedom

I found this quote, from Cardinal Ratzinger's recent comments in La Repubblica, in the "Signs of the Times" section of a recent issue of America.  Commenting on a "worrying" "aggressive secular ideology," he said: 

"Laicism is no longer that element of neutrality which opens up spaces of freedom for all.  It is being transformed into an ideology which is imposed through politics and which does give public space to the Catholic or Christian vision, which runs the risk of becoming something purely private and thus disfigured.  In this sense, a struggle exists and we must defend religious freedom against the imposition of an ideology which is presented as if it were the only voice of rationality, when it is only the expression of a 'certain' rationalism."
