Few die of normal flu, because many are immune. And if no people are immune, then more will die. Covid-19 is no different than Spanish flu.
You seem to agree that they are totally different, except that "no people were immune". Even if that were the case (it is not), that still makes them different
This is like saying that a fast car and a slow car are exactly the same, except that the fast car has stuff inside it that makes it go faster. Total non argument.
At least not very significantly.
I am not sure what game you are playing here. First line of YOUR link: "The Spanish flu [...] was an unusually deadly influenza pandemic". Not ordinary, unusual.
As for your " Only no one was immune to it", that is like saying having your head chopped off is not dangerous, except for all the stuff in your neck that gets ruined. Total nonsense
That link also talks about especially young adults dying from it, which is an extremely uncommon thing for the normal flu. It behaved in a special way.
