My grandmother went to a Presbyterian church from the 1960s through the 80s (just that I know of) and she would turn over in her grave over this.
There are plenty of good Presbyterian denominations. Presbyterian Church of America, the Evangelical Presbyterian Church, and the Cumberland Presbytherian Church. They are all growing; the PC-USA is shrinking.
Problem is that the press lauds them because they are a failed church, and they are also the oldest with the prettiest buildings.
