You make an interesting point. It may be true a modern American mind set isn't appropriately trained to make the correct distinctions, but that just puts us back to the position of a "weak" brother as in 1 Corinthians. It does not fix the problem.
As for your inability to appreciate my discomfort, I would think praying my life and my hope to anyone but God would be fairly self evident.
Well, I'm a 21st Century American like yourself, with all the cultural limitations that entails: distant from the richness of the High Middle Ages, and even more distant from a Patristic or Biblical sensibility.
I don't find that all Marian devotions appeal to me emotionally or aesthetically. I have had to ponder a lot, sometimes in puzzlement, and for years; in fact, quite often when I pray the Rosary I ask the Holy Spirit to help me to better understand and grasp these beautiful and mysterious things.
But if "my life, my sweetness and my hope" distracts you to the point where you're irritated and disturbed, by all means choose some other text. Fr. Benedict Groechel says, "Pray as you can, not as you can't." Amen to that!
