While personally I would favour an absolutist separation of church and state like in France, I can see some logic in other options. The German argument goes that if religious education and finances go through the state, that also means some control by the state, which results in keeping those religions moderate and open. The few fundies in Germany (including US-inspired creationist evangelicals) do indeed want to close off and build their own separate infrastructure.
