LarryD over at Acts of the Apostasy has identified several heretofore undiagnosed medical conditions afflicting dissident Catholics.
Thus far Larry has identified five such maladies, with Cataractechesis being my favorite.
Cataractechesis - this is a vision problem with dual symptoms: seeing things written in the Catechism that aren't there, and not seeing the things that are there. A derivative of this illness is Scrapture, where Biblical passages that challenge the patient's questionable lifestyle choices are scrapped.
