No disrespect intended but there really is ample evidence both from scripture and the original leaders of the church to realize Mary was blessed, but Jesus was the blessor. Mary was a sinful human just like you and me.

No one is denying that Most Blessed Trinity is the blesser of Mary, but the argument is over whether she sinned and there is some disagreement over that. I trust the teaching of the One, Holy, Catholic, and Apostolic Church, whose authority is derived from the authority of God Himself.

And God Himself gave us the Bible with his teachings:

“for all have sinned and fall short of the glory of God” (Romans 3:23).

There is no exclusion for Mary and God would not say "all" without meaning all,
