The “Francis baptism” and the “O’Malley dabbing”, both of which actions I regard as canonically licit, have occasioned from observers who regard themselves as Francis-O’Malley champions some defenses that, I fear, indicate considerable ignorance (not ill-will, just ignorance) on their part about how sacraments and sacramental signs are supposed to work in the Church.

When we argue in favor of a practice we should take care that we don't harm other important practices or principles.
