I have been worried about the increasing influence of churches in America in the past few years. This may seem odd, since religion — particularly Christianity, particularly Protestantism — has always had some level of influence in America. I find it annoying the extent to which especially right-wing evangelical Protestants have shaped our national discourse. They do this while getting quite a number of tax benefits.
Fundamentalists scream all the time about the Free Exercise clause of the First Amendment (usually declaring that this entitles them to push religion — or their particular view of religion — into all sorts of civic places) and completely ignore the second part, the Establishment clause. Nice to see someone remembers it.
