Those who seek to mislead unbelievers into believing Mary is Divine, providing attributes to God, as implied by the title of Mother of God, without well stipulating they only refer to her providing the motherhood of His Incarnation, will naturally claim they are innocent and have no idea of how they are telling a tale.
I do not know your heart nor your intent, but the words without stipulation, “mother of God”, implies Divine attributes to the mother being passed to her son.
I find Mary as blessed and I rejoice in what God has provided us and her, and the best form of respect for her is the proper worship of Christ Jesus.
No harm no foul - except I wouldn't say 'mother only of His incarnation' because that seems to make Jesus into God-lite. I am sure that is not your intention, but it is the slippery slope of language. Jesus was/is was all God and all man, and the Incarnation is a every bit as much divinity as God the Father or God the Holy Spirit. So I punt on unsnarling the God-Man mystery but don't retreat on the title 'mother of God' precisely because Christ is God and an equal part of the three-in-one Godhead, and he was born of Mary, who said 'yes' to God and was blessed above all women for it and who humbly brought into history the source or our salvation.
