When sales of hot chocolate go up, street crime drops.
Sorry, I have got no time and no patience for any such discussion that always focusses on individual points and hence drifts away from the little objectivity and common-sense that can be expected from such exchange. Unfortunately, there simply isn't a common-sense answer for many questions, but that doesn't mean that one shouldn't at least try to aim for it. And yet, kale is kale and lettuce is lettuce and if there is no point to that difference I don't know where it is.
I've given all needed information so far. If there are more questions, feel free to ask.
