I don't think little Robert was shown the secrets of the rectory either, for the record. What I do wonder is if he took offense to the molestation personally, not because he was so offended on behalf of the abused kids, but because it resulted in other kids making fun of him for his religious affiliation. Robert has a weird relationship with Catholicism where despite his militant fedora tipping he can be oddly tribal about it. A while back he re-Tweeted a post about this communion wafer "gun" that was designed for social distancing of communion and he basically said, "LOL, get rekt protestants, you don't have cool shit like we do!"
It makes me wonder if he considered Catholicism a proud part of his identity in his younger years, then it became an object of scorn in his community because of the molestation and he turned on it, becoming extremely anti-religion (except Islam, because he's that big of a two-faced pussy) and "fuck yeah science" mainly as one of his many misguided attempts to be popular. Completely realigning his beliefs that seemed deep and strong based on who he perceives as being the harbingers of the superior future, IE- the winners, is something we've seen from Robert before, after all. He used to think Hillary was "quite evil." Now he thinks people who believe that are subhuman.
