why the separation of church and state?

Why the need for separation of church and state? some of you know and some of you don"t. If church and state are combined you get the Middle Ages, the Taliban, the flight to America seeking religious freedom. It does come down to freedom. You can't have true freedom under a religious state. All religions operate from dogma(the Truth as they see it). If the dogma is questioned for example with the question Why? it creates fear (fear of the shattering of dogma).

The truth is that when religion begins to creep into government(state) it will begin to shatter the most precious thing in the world. FREEDOM. Make no mistake because it is historically TRUE. When church and state are combined there is and can be no freedom.
