I agree with Tom Butler, Baptists are not Protestants, although they were known by a variety of names through the centuries. There have always been "Baptists", those known as "the people of the Book".
Going back to the original subject, I think a big part of the problem is that we have it too easy in America. This can be seen in the OT as well. Whenever Israel was blessed and in prosperity, this is when they tended to depart from God. Whenever they were persecuted, they returned to God.
I don't think folks are "playing church", they are simply distracted by the world. They are the seed grown up among thorns. I do not believe these persons are lost, but they bear no fruit for Christ.
If our government were to persecute Christians, you would see the real believers come out. They might meet in secret, but they will come back to the church.
