Nobody says it does.
Many people DO worship Mary and artifacts.
We have to make many distinctions in our lives to keep straight on a multitude of issues, not just religious matters.
Many people DO worship Mary and artifacts.
No doubt some do, but it's because of ignorance. How many and which ones do by external observation is impossible to say unless one is a mind reader. I may see me kneel down in a posture of prayer before an image of the Blessed Virgin Mary, but I assure you I am not worshipping her (or the image, for that matter) as I do God because the Bible and the teachings of my Church explicitly forbid it.
