About the praying to Mary, all you can say is that you and maybe some you know do not pray to Mary, many I know do indeed pray to Mary and Worship mary. Frankly some of the most Godly/Holy peole I know do this.
You give yourself way too much credit and I probably contribute to it by even responding to it. Your intellectual arguments are weak which doesn’t drive me crazy but your lack of knowledge presented as if it is factual is frustrating.
However, for the sake of clarity, any person who worships the Virgin Mother of God is violating the Teaching of the Catholic Church. While I know numerous people who have a devotion to Mary, none of them worship her. They only worship the Trinity. Intellectually, you should know the difference between venerate (which is what Catholics do to Mary and the Saints) and worship (which is solely reserved for God).
Prayer has multiple dimensions beyond making Prayers of Praise to our Creator, Savior and Paraclete.
Prayers of Petition (essentially making a request) can be to God, Mary, the Saints or even my neighbor to intercede on my behalf. There is nothing wrong with asking my neighbor to mow my yard during my vacation, asking Mary, my wife or the hospital janitor to pray for me at the hour of my death, or asking God for guidance or Peace. For me though, it is trivial to ask God to help me sell my house but I have no trouble asking my friends, neighbors and even St. Joseph to help me get my house sold. Just as I don’t ask God to mow my yard, I guess for me the distinction is God should be asked only for the most important things and leave the rest to the rest. If you think it appropriate to ask God for the big things and the little things, go for it.
Prayers of Thanksgiving can be done to God but they can also be done to Mary and the Saints as we express our gratitude for their intercession on our behalf (similar to expressing gratitude for my neighbor who mowed my yard).
Prayers of Contrition (request for forgiveness) are not only done to God but we should also request forgiveness from our neighbors against whom sin.
It is so tiring to listen to people who say that we should have a personal relationship with Christ yet think it is ok for us to ignore and even disrespect his Mother. My relationship with my wife is enhanced by me loving, respecting, and intimately getting to know her mother. When I pray to Mary, I am sometimes reflecting on her life as a perfect Disciple of her Son, am sometimes asking her to petition to her Son on my behalf (sometimes when I want something from my wife, it is better to work thru my mother-in-law. Keep in mind that Jesus did as Mary ordered Him to do at Cana despite the fact that “His time had not yet come.”), and am sometimes just “visiting” with the mother of my Savior (not only does my mother-in-law have insight into my wife but I respect her wisdom on other matters. Similarly, Mary has insight into her Son as well as great wisdom into Christ’s desires for me).
