I am not a big fan of bacon, I prefer iberian ham or york ham but it is not that bad.
I just think that the point of a salad is to have a healthy meal so it is better to use lean meat
Because "rich, prestigious" ham > "poor, fat people" ham
Plus, the fat is rendered down when it's crispy. All it would do to a salad is add a smoky flavour. Even if there is fat on rendered-down crispy bacon, I assure you, it's not much.
