We may not have a complete picture of the immune system but one of these comments is square in the realm of "not science but sounds pretty good" and one at the very least in the ballpark of "conventional science we learn in school". Even if the former turns out to be correct several years from now it won't have been because of the revolutionary new hypothesis first put forth in an HN comment. They've done something we all do where we draw conclusions from our own experience which frequently turns out to be absolutely bullshit. Humans tease out patterns where there are none.
