Do you find your honor of your father and mother, or the honor of the angels and saints, or the honor of other honorable persons, and the adoration of God, to be a "distinction without a difference"?
I assume you'd say "No," you don't have a problem in general distinguishing honor from adoration. If that's the case --- and if you don't mind explaining --- what's the particular problem with Mary?
I find the Catholic comportment toward Mary to be "adoration" while that toward God to be "fear and reverence."
