No Catholic worships MAry no matter how much you might like that they do. Do you not know that even Christ Himself asked His mother for things? He wants us to do the same.
In a grassy field about 5 miles from my house there is a statue of Mary. The field is across from a Catholic facility, and is the venue where some vision of Mary was spotted some time in years past.
People go out into that field and bow down to that statue, then they get up in put money into a roofed and padlocked box with a wire mesh around it.
I don't like to think anyone is involved in idol worship and sacrifice thereto, but I have a hard time calling this anything else. Sorry.
