Oh, that accusation -- one is DEMONIZING certain foods! In this give-everybody-a-chance-to-screw-you-over-or-else-you're-being-UNFAIR culture, one can't even point out that certain foods are in fact BAD FOR US without some junk-food apologist protesting (too much)....
Face it, there's a lot of edible items that do horrible things to our bodies. Pointing them out is not demonizing them. The D-word is an emotion-charged appeal designed to get us to BACK OFF.
Too much lettuce in my diet makes me feel bad, as do a number of other vegetables. Gluten-grains are problematic for me too, as well as some dairy products and megadoses of nightshades. Ditto for certain man-made additives. I report my observations as a heads-up to others. Does this mean i'm DEMONIZING them? Some people would say yes -- probably some of the same ones who go around "demonizing" red meat. ;-) I scoff.
Next time you read that word, take a mental step back and dispassionately consider what this appeal to your emotions is trying to achieve. I suspect you'll find that it's an industry-promoting attempt to defend an indefensible product.
