Another un-American activity they are engaged in is to support rolling back the Separation of Church and State. They endorse Christianity as a state religion by sending large amounts of tax dollars to religious organizations sympathetic to their cause.
They are not "endorsing Christianity", they are buying off the Churches. Churches are the conscience of the nation, yet Churches are run by men and men are hesitant to bite the hand that feeds them.
Remember, the Separation of Church and State is not to protect the State from the Church, it is to protect the Church from the State.
