Again, anti-Judaism is not the same thing. This is just "normal" religious persecution that has been around since forever and that many (if not all) religious groups have experienced at some point or another. Does this matter? Well, in the context of discussing Nazi world-views it does. None of this is especially controversial among mainstream Jewish historians, as far as I know.
I think you're trying to draw a hard line distinction where only a blurry evolution exists. While antisemitism in the 19th and 20th centuries had some unique characteristics that co-evolved with other forms of racism, antisemitism existed before the 19th century and there are clear evolutionary roots e.g. "Jewish badges" [1] that date back to the 1100s, which the famous "Jude" badge from the Nazi era was a continuati…
Depends on your your definition of "antisemitism"; if you mean "general prejudice against Jews", then sure, obvious that existed. But if you you mean "anti-Semitism against the Semitic race (as opposed to the Aryan race)", then that's quite a different thing.
I don't think it's a hard-line distinction; obviously there's overlap and nuance. But the move from more or less generic religious persecution to racial-based persecution was a very marked and notable shift that many many people have commented on, and that's really not very controversial.
Does this distinction matter? Well, it seems to me that it does. I don't think the holocaust would have happened without this. And all of this strongly shaped Nazi world-views, which was really the point I wanted to make.
