Respect, without a doubt, but not worship.
Would you like a scriptural reference to help you understand this? See Luke 1:41-43. When she met Mary, Elizabeth was filled with the Holy Spirit. While filled with the Holy Spirit, Elizabeth cried out, Who am I that theMOTHER OF MY LORD should come to me? Under the inspiration of God the Holy Spirit, Elizabeth calls Mary the Mother of the Lord. The Lord is GOD, my friend. She didn't say "mother of the messiah" or "mother of the Savior" or "mother of that part of Jesus which is human". Do you think that the Bible is wrong on this point?
With regard to your contention that Mary was a sinner, just like all other human beings, again you err. The angel Gabriel greeted Mary with the words, "Hail full of grace". Grace is the "freely given and unmerited favor and love of God." Alone among creatures referred to in the Bible, Mary is "full of grace". She could not have complete and full frienship with God unless she had never sinned. Why do you deny this? Do you think it is impossible for God to create a human being, preserve that person from original sin, and give that person the grace to avoid all sin during their life? And, if God were to create such a person, can you think of a better person to receive such a great favor than the woman who would be the mother of his only Son?
I truly worry about people like your self who seem to have a visceral hostility toward Our Lady. When you appear before Jesus, as will we all, how do you intend to explain the neglect, if not outright hostility, you demonstrate toward her? I guarantee you that Jesus loved her more on earth and loves her more in Heaven than even her most ardent devotee on earth could love her. Why not follow his example?
