God is one substance. I.e., God the Father and God the Son are not two beings. God the Father, God the Son, and God the Holy Spirit are not three beings.
Mary is the mother of the Second Person of the Trinity, and not the mother of the other two Persons of the Trinity.
You have simply asserted that God is one, and IGNORED the distinction of the PERSONS in God. I.e., in order to deny Mary the title of Mother of God, you have denied the TRINITY.
This is what always happens on these threads: Those who deny Mary the title of Mother of God always end up denying one or more fundamental dogmas in Christology, or they end up denying fundamental Trinitarian dogmas. They have to split Christ into separate beings, or they have to smudge the Persons of the Trinity into a single blob.
Anyway, your Trinitarian theology and your Christology would get you burned at the stake by Luther, Calvin, Melancthon, Cromwell, etc., etc.
So you're saying here that the second person of the Trinity did not come into existence until Mary conceived Jesus in her womb.
That means He is not eternal, that the claims that He has no beginning or no end are false, that He is not co-equal with the Father and the Holy Spirit ergo, He is NOT God.
Sure they are...And yet they are one being...Jesus said the Father was in him and he in the Father...Yet while on earth, Jesus prayed to the Father in heaven...So explain that...

Could be, but they were Catholics anyway...
