The irony here is that Revelations is the only book in the Bible not canonized by the RCC.
I have no idea where you are getting your information from, but Revelation is MOST DEFINITELY part of the Canonical Scriptures!
It would be very good to have a good grasp of the basics from which to argue from.

The Council of Florence, also called Basel, 1431-1445,
SESSION 11 4 February 1442:
"We, therefore, to whom the Lord gave the task of feeding Christ's sheep', had abbot Andrew carefully examined by some outstanding men of this sacred council on the articles of the faith, the sacraments of the church and certain other matters pertaining to salvation. At length, after an exposition of the catholic faith to the abbot, as far as this seemed to be necessary, and his humble acceptance of it, we have delivered in the name of the Lord in this solemn session, with the approval of this sacred ecumenical council of Florence, the following true and necessary doctrine. Most firmly it believes, professes and preaches that the one true God, Father, Son and holy Spirit, is the creator of all things that are, visible and invisible, who, when he willed it, made from his own goodness all creatures, both spiritual and corporeal, good indeed because they are made by the supreme good, but mutable because they are made from nothing, and it asserts that there is no nature of evil because every nature, in so far as it is a nature, is good. It professes that one and the same God is the author of the old and the new Testament -- that is, the law and the prophets, and the gospel -- since the saints of both testaments spoke under the inspiration of the same Spirit.
It accepts and venerates their books, whose titles are as follows. Five books of Moses, namely Genesis, Exodus, Leviticus, Numbers, Deuteronomy; Joshua, Judges, Ruth, four books of Kings, two of Paralipomenon, Esdras, Nehemiah, Tobit, Judith, Esther, Job, Psalms of David, Proverbs, Ecclesiastes, Song of Songs, Wisdom, Ecclesiasticus, Isaiah, Jeremiah, Baruch, Ezechiel, Daniel; the twelve minor prophets, namely Hosea, Joel, Amos, Obadiah, Jonah, Micah, Nahum, Habakuk, Zephaniah, Haggai, Zechariah, Malachi; two books of the Maccabees; the four gospels of Matthew, Mark, Luke and John; fourteen letters of Paul, to the Romans, two to the Corinthians, to the Galatians, to the Ephesians, to the Philippians, two to the Thessalonians, to the Colossians, two to Timothy, to Titus, to Philemon, to the Hebrews; two letters of Peter, three of John, one of James, one of Jude; Acts of the Apostles; Apocalypse of John."
By your comment you are stating that there is a coredeemer and diminsihing the effacy of Jesus. If I was an inquiring preconvert, I would pronbably also not want to be a Catholic if I felt you were representative of the what Catholics believe.
Since we see that there is poor understanding of even the basics such as what is and is not canonize scripture in the Catholic Church, it is becoming apparent that such criticisms don't hold a lot of weight or vaidity and only further demonstrate a very serious error in understanding what the Church teaches on the matter and what others are saying in defense of Church teaching.
no one here would want you to blindly adhere to anything. But..I think if you were to research how we look at Mary some more..and really pray and open your mind..and look at the terms from our perspective, not from the Protestant perspective.. you might see a different picture. 
Somewhere along the line the Catholic Church went astray with such teaching. "
