A "fight" takes two, ya know.
Rather than assume that those with whom you disagree, "just don't get" it, why not try to see all sides? You have strong feelings about what you believe, so do the others. No one needs to make it into a fight, when adults can discuss these things respectfully. Just because some disagree with some of the doctrines in Catholicism, it doesn't mean that there isn't also agreement with some of them. Lastly, remember that Luther was NOT the first, NOR only, person who saw the condition of the Catholic Church at that time as needing to be reformed back to the original orthodoxy...you know, the Bible.
Luther was a creep - why do you like him?
I am exhausted I have been trying.
