No, the real irony is that the statement comes from someone who belongs to a religion that has developed Marian devotion, Marian Mediatrix, Marian co-redeamer, Marian Queen of Heaven completely outside of the scriptures...
You have a vested interest in not accepting Sola Scripture...
Exactly the opposite is true. Protestantism has a vested interest in establishing sola scriptura because it is the only way that it can control the dialog at the expense of the Holy Spirit. Sola Scriptura cannot be established based upon scripture.
When challenged Protestants make the argument that to suggest that scripture does not contain 100% of the revealed word of God is to challenge the credibility of scripture. The Catholic position is that scripture is 100% accurate, but not 100% complete.
Protestants claim that scripture is both 100% accurate and 100% complete, but require the belief in the extra-Scriptural Sola Scriptura argument to defend it. Dizzying to say the least.
What basis do you have for declaring, simplifying, or summarizing what the Catholic Church does or does not teach or what Catholics do or do not believe since you admittedly have never studied any of the Catechism? Back in the hood they would call what you are doing 'talking out of your you-know-what'....
So does Scripture.
