Not really. Other people are reading the thread, and those other people may have been influenced by Luther and his fellow Protestant leaders. Still others may not be aware of what Luther wrote, and may bring other questions to mind.
If a person debating the beliefs of the Catholic Church doesn’t understand the significance of Luther and the rise of non-Catholic Christians, then there really can’t be much of a discussion.
Modern non-Catholic Christian theology, generally speaking, isn’t a product of today, rather it is a product of the Reformation and forward. Knox, Zwingli, Calvin, and Luther didn’t walk in lockstep, they required each other to act as foils off which they defined their own beliefs. Luther used the Catholic Church as his foil. However, there are foundational teachings shared by Protestants, not shared by Catholics, as well as foundational teachings shared by all Christians.
And just for fun, should one be a Calvinist and believe the “call no man father” thing, here is what John Calvin called Martin Luther:
“Adieu, most renowned sir, most distinguished minister of Christ, and my ever-honoured father.”

Phoooey!! The only reason Catholics depend so much on Luther is that they can't defend their beliefs with scripture alone. They have to change the timeline thinking they then establish that base as before Luther. Luther is nothing more than a straw man for them. If Catholics could defend their beliefs with scripture they wouldn't need Luther.
