I still think it was just an excuse. No doubt Dreher did become too emotionally involved in the sex abuse scandal and if he was talking only to the alleged victims, he would end up getting a very one-sided picture of this. Some of the allegations of clerical sex abuse are false. Moreover, only a small percentage of priests have been accused of abuse. The rest of them faithfully carry out their ministry. To be so scandalized by the actions of a small number of priests while ignoring the good done by the rest of the clergy is wrong. It's an over-reaction born of self-righeousness. In other words, Dreher is blaming the whole Church for the actions of a small number of men. The Church is no longer "pure" enough for him and so he left. I can't condone his decision.
Yes, this is certainly true; but over 60% of the Bishops admittedly transferred known abusers from parish to parish without any warning that he was a pedophile (or ephebophile or "gay guy who liked the young stuff" or whatever you want to call it.)
Look, I don't condone Dreher's decision to leave the Catholic Church. But to say he is "ignoring the good done by the rest of the clergy" is simply false--- he has not done this at all; and to assume he is "self-righteous" is a rash judgment: falsehood and rash judgment both being moral offenses which could use some careful examination.
This may give you a more accurate and at the same time more merciful view. Read recent entries on Dreher's blog, especially "Gratitude" and "Ave Maria, Gratia Plena."
Peace to you.
