I never run into the forced anarchy while playing in democracy. But in CCM the setting for war weariness is the same as in standard C3C: The war weariness is high. But in CCM wars in democracy can last much longer due to the additional possibilties for happiness (additional religions, world religion and "cathedral boosting" possibilities). So in my eyes, if you have access to at least two religions, in CCM democracy can be a very considerable government. In my current CCM game I´m in democratic government since it was available, I´m always at war with differnt civs and it´s working great as I also had access to another religion and a worldreligion.
