You perhaps think your identity as a Christian is essential to your identity and actions as a citizen, because—though Christ’s kingdom is not of this world—you are a Christian citizen in a country that is made a nation by the rule of “we the people.” Thus, being your authentic self just like a good liberal, you believe you are your best as an American when you don’t hide your faith in public, especially in participating in political life. You are a good citizen because you try to be a good Christian, and it wouldn’t occur to you to pretend that’s not the case. You probably think America has been “a Christian nation,” or at least had a Christian society, and that God has blessed this country.
That is the right’s current conclusion, but not really, no.
