I'm planning a ritual ceremony because I believe ritual oomph is important. I'll be debating that later, but not now.

I do think your overall point here is pretty solid though. The only thing that gives me pause is that I don't think the lesson behind the Litany is wrong. I think one of the arguments the Litany uses to express its point is untrue.

Part of rationality is discarding untrue beliefs and letting go of old teachers, but another part is being willing to look at something you believe, identify individual bad arguments for it, and then removing those arguments without feeling like you're stabbing yourself in the back.
