Nobody's doing that. Recognizing that God blessed Mary in unique ways certainly doesn't do that.
Mary cannot bless us.
She can do nothing for our salvation.
We are not to adore her or venerate her.
Did God use Mary in a special and unique way? Yes.
Was she a sinner like us? Yes
Did she have need of salvation like us? Yes
anything beyond that is outside of the Bible and based on man’s tradition.
