"3 And when they ran out of wine, the mother of Jesus said to Him, "They have no wine." 4 Jesus said to her, "Woman, what does your concern have to do with Me? My hour has not yet come." (John 2:3-4)
"47 Then one said to Him, "Look, Your mother and Your brothers are standing outside, seeking to speak with You." 48 But He answered and said to the one who told Him, "Who is My mother and who are My brothers?" 49 And He stretched out His hand toward His disciples and said, "Here are My mother and My brothers! 50 For whoever does the will of My Father in heaven is My brother and sister and mother."(Matt.12:47-50)
Mary was chosen by God to bring Jesus into the world, and in that she was blessed among women. But Mary was still human, still needed a savior, and is but one of the body of Christ, as are all Christians. It is not contempt of Mary to recognize this fact, but simple acceptance of what the Bible clearly states.
You're not going to be worshipping or praying to Mary with that attitude. Good for you.
