Question

"Who is this fellow, the Holy Ghost? Doing unholy things, making a poor virgin Mary pregnant, still he remains the Holy Ghost!"

Answer 1

That is the Holy Spirit you're talking about. And why in the world would you refer to Mary as "poor"? Mary rejoiced to be blessed as the mother of Jesus, and everyone knew it.

Luke 1:39-55

39At that time Mary got ready and hurried to a town in the hill country of Judea, 40where she entered Zechariah's home and greeted Elizabeth. 41When Elizabeth heard Mary's greeting, the baby leaped in her womb, and Elizabeth was filled with the Holy Spirit. 42In a loud voice she exclaimed: "Blessed are you among women, and blessed is the child you will bear! 43But why am I so favored, that the mother of my Lord should come to me? 44As soon as the sound of your greeting reached my ears, the baby in my womb leaped for joy. 45Blessed is she who has believed that what the Lord has said to her will be accomplished!"

Mary's Song

46And Mary said:
"My soul glorifies the Lord
47and my spirit rejoices in God my Savior,
48for he has been mindful
of the humble state of his servant.
From now on all generations will call me blessed,
49for the Mighty One has done great things for me—
holy is his name.
50His mercy extends to those who fear him,
from generation to generation.
51He has performed mighty deeds with his arm;
he has scattered those who are proud in their inmost thoughts.
52He has brought down rulers from their thrones
but has lifted up the humble.
53He has filled the hungry with good things
but has sent the rich away empty.
54He has helped his servant Israel,
remembering to be merciful
55to Abraham and his descendants forever,
even as he said to our fathers."

It doesn't seem like you're getting the story of the Virgin Mary at all, and perhaps a lot of the bible. You really need to study the bible more to better understand the messages in it.
