Scripture contradicts you.
"And whence is this to me, that the mother of my Lord should come to me?" Luke 1:43
God has no Mother.
God Incarnate does, just as Scripture teaches.
I would love to see you use Scripture to show how insulting Mary equated to insulting the Lord Jesus Christ
"For Moses said: Honor thy father and thy mother; and He that shall curse father or mother, dying let him die." Mark 7:10
Scripture is wasted on the obtuse just as St. Peter wrote.
"And account the longsuffering of our Lord, salvation; as also our most dear brother Paul, according to the wisdom given him, hath written to you: As also in all his epistles, speaking in them of these things; in which are certain things hard to be understood, which the unlearned and unstable wrest, as they do also the other scriptures, to their own destruction." 2 Peter 3:15-16
First, there is a big difference between the use of Mother of God and mother of my Lord. Mother of God is a proper noun while mother is a common. God is Yahweh, I am who I am, the Greek for Lord in this verse is master, not LORD as in Yahweh.
Second, do you not remember when Christ on the Cross rejected His mother’s claim to Him? In a sense, transferred such mothership to John? He wanted to ensure no one would deify or worship her. She was just as human as the rest of us.
Third, you are taking that commandment out of context. The son or daughter is commanded to not curse the father or mother. I am not the son of Mary.
18“What profit is the image, that its maker should carve it,
The molded image, a teacher of lies,
That the maker of its mold should trust in it,
To make mute idols?
19 Woe to him who says to wood, ‘Awake!’
To silent stone, ‘Arise! It shall teach!’
Behold, it is overlaid with gold and silver,
Yet in it there is no breath at all.
20 “But the Lord is in His holy temple.
Let all the earth keep silence before Him.”
