Ahh a protestant, someone who listened to a heretic like Martin Luthor whose words are worse than shit from a horses ass. That might explain why you don't know anything about Church history, or even the religious history of Israel. Here is a hint, sola scriptura is false. You need the tradition of the early Church.
It has nothing to do with being a Protestant. You have at least one Protestant (Battlegrinder) in this very thread schooling the person on Christian theology soundly who's expressed the underlying theology more thoroughly than any of the Catholics or Orthodox posters have, who mostly seem to be content just sniping at "Protestants" even while said Protestant does the heavy lifting in argument.
No, it has to do with the fact that Lutheran is a "Mainstream" denomination in the US. Mainstream denominations in the US, which includes Catholics by the way, seriously lost their way starting in the 1920s and 30s with the Modernist / Fundamentalist split, where the Modernists decided small unimportant things like "Christ wasn't a real historical person" and "miracles didn't happen" were more important and that Christianity was more about the "social gospel". They utterly lost their way theologically
starting with the colleges meant to teach pastors, meanwhile the Catholics lost any and all spine, allowed homosexuals to use their schools to hide in and then making them priests and enabling them to abuse children all while actively covering it up, so don't pretend being Papist makes you any better. Anyway, it makes sense then that a layperson coming out of that tradition would have an utterly incomplete understanding of theology and scripture.
This is also why Battlegrinder is able to explain things accurately to the point where he's a Prot you likely didn't even notice. He's from the Evangelical sect of Protestant Christianity in the US, who are descended from the Fundamentalists of the aforementioned Modernist/Fundamentalist schism, which retained an orthodox understanding and placement of Scripture and theology.
Also, you really have a misconception of what Protestants accept. Protip: Protestants, especially of the Evangelical strain, DO study and adhere to early Church tradition, and most hold that to be considered Christian one must also agree with the Apostle's Creed and the Nicene Creed (it's constantly reprinted in Evangelical Churches). Are there Protestant sects that reject them? Sure, and most other Protestant consider those groups to be at best, non-Christian to at worst cults (IE Seventh Day Adventists and Mormons have rocky relationships with other Protestant-descended denominations).
But I'm sure that doesn't matter, since it seems you don't care about theology, you seem more to care about dissing on Prots, even while it is Prots fighting on the front line of the culture war while your precious Papal Church sits back and virtue signals to the Progressive Left that it really isn't so bad, look the Pope cares about the Environment and holds Capitalism to be a worse evil than Communism! Ain't you hip and cool?! Oh sure, you hold that Abortion is a terrible Sin against Goid, but can't be assed to actually take a REAL stand on the topic by Priests and Bishops by excommunicating or at least denying communion to politicians who continue to support it institutionally, that would be CRASS and might result in losing your precious TAX BREAKS.
Give me a break, this constant dunking on Prots by Catholics and Orthodox is some of the most transparent cope I've ever seen. Yeah, sure, Evangelicals have issues, but they're at least actually still fighting.
