Well, yes, my mother is a minor player in my life, but that has nothing to do with Mary or her role. Re-read the OP and notice that she is just an ordinary girl selected for an extraordinary task. But, the task is to bear the real Extraordinary Person into His incarnate state. And, all eyes should be on Him...not her. Calvin, Zwingli, Luther notwithstanding. And, the kind of inordinate adoration given her by Rome is part of what makes Rome a broken organization. The rest comes from the other errant, non-biblical doctrines promulgated by her.
Yes, the gospel is all about Jesus. However, there are special people in Jesus' life. Jesus has a unique relationship with Mary. She is His mother.
Is it possible that you see Jesus only as God but marginalize His humanity?
