The letter itself contains nothing objectionable, but it's a bit rich that Dreher would post it considering his apostasy from the Catholic Church due to his emotional reaction to the Scandal. Years later, he still writes about the Church frequently, generally to remind us how awful it is and that he's really not coming back. Dreher has said that he's trying to keep the scandals of the Orthodox Church at arms length. He satisfies his appetite for drama by focusing on his former communion. Sometimes I get the impression that Dreher is still trying to convince himself that he made the right decision; his stated difficulties with papal infallibility were clearly an ex-post facto rationalization.
I've made no secret of my disgust with many corners of the Church of Nice as Michael Voris calls it, but in the end the only question that really matters is, "Is the Catholic faith true or not?" If it is true, then no amount of scandal, hypocrisy, or evil committed by Catholics can make the faith untrue. Granted, it can make it subjectively more difficult for us to persevere, but to whom else would we go?
