Nobody is saying the Blessed Mother didn’t need a savior.
That doesn’t mean She was sinful. Do you deny She bore the Son of God? If the Holy Ghost is not sinful, why can’t the virgin mother of God not be sinful?
Show me where, in the Bible, Mary was baptized in order to remit original sin.
As it turns out, Mary is not God.
You’re entitled to your beliefs and have attempted to defend them admirably but please don’t devolve to playing word games. Savior implies salvation, and salvation would be from what? Sin. I profess what is written and know what is, and what is not written. Contending that Mary was of necessity sinless in order to have borne the Son of God is in direct contradiction to scripture. She was a virgin who conceived via the Holy Spirit. She needed a savior. Beyond that lies conjecture, all of which contradict other passages of scripture and therefore it is unacceptable. Sorry.
