An interesting comment. Can you give some definitions (e.g. what is fundamentalism...at least, the fundamentals, so to speak) and some examples?
Cardinal Schonborn said it was important to realize that Darwin's theories continue to have an impact in economic as well as biological fields. For example, he cited a link between ideological Darwinism and some capitalist theories that consider high unemployment simply a byproduct of a necessary economic natural selection.
Obviously Schonborn isn't a fundamentalist. And I only use the term as they apply it to themselves.
I don't have any cites handy, I was just stating my impression. More so from the fundamentalist desire to regulate everyone elses behavior, less so from a direct anti-capitalistic attack. So I think their socialism is more along behavioral lines rather than strictly economic. But in the end, the results are similar.
