So many NCs are driven wild by the assigning of such titles as Queen of Heaven or Queen of Angels to Mary. The title Mother of God is seen as no less than blasphemy. So they go to the other extreme and beyond and reduce Mary to a cipher.
Who does this? It is news to me. While you claim "so many", I'll settle for just a few.
It is not Catholics who have given Mary her place but God. It is He who has called her to come to the head of the table.
Scripture?
Try the first two Chapters of Luke. But then we see the futility of Sola Scriptura since those who different theologies in the first place will not find the same meaning in the words they read.
