wow. Direct parallel. In all of my dealings with my family yelling at me for being an apostate it always ends with the same thing at the end. "if its not the truth I have wasted my life". Its a strange admission, because everything else they say, 99% of the conversation is about bad mouthing me for not believing in god, and why the org is where its at, but inevitably, usually with tears, they make this admission. Basically all they have invested is lost.
People believe in Xenu and thetans because it becomes exceedingly difficult not to in light of all they have committed to the church.
So when I read this I hear that subtle admission they all slip into the cognitive dissonance rant. They are overly invested. its insane.
