Nonsense prayers in the sacred liturgy are never "just fine."  Meaningless liturgical prayers insult both the Faithful and God almighty, for God is the Word, particularly in the very Liturgy of the Word.  Child abuse is  a monstrous, pandemic evil and the source of lifelong suffering; but so is abuse of the Word.  Both happen to humans, but one is about other humans, the other is about God Almighty, the Word.
