Your post in 30 is awesome. Mary is the greatest role model of Motherhood so yes she must weep bitterly over abortion.
I would like to share a website directly related to Mary, abortion and the long history of ritual killings of men, women and children in human sacrifices http://www.sancta.org/
Of particular interest might be: “Protectress of the Unborn”
on your post: Just one note for clarity. The Catholic Church has never taught or even proposed the idea of worshiping Mary. It does teach that Jesus is as much Mary's Lord and Savior as He is ours. Mary herself worships Jesus and the Triune God. Just as friends and relatives petition one another for prayers, we petition Mary because as the Mother of our Lord we realize she is closest to him; and no Good Son ignores His mother.
I mentioned ‘worship of Mary’ on purpose since it shows up so many times as a specious accusation toward Catholics relating to The Mother of Our Lord.
