I haven't owned a scale in a decade. My belt tells me what I need to know. I think people worry too much about the numbers and gloss over the actual fitness, and that's what leads to things like anorexia, steroid abuse, and a ton of other disorders/addictions. Healthy doesn't have an exact size.
That said, I kinda agree about the thin being 'bad' these days. It's been that way for men for a long time (don't be the scrawny guy or you must be a geek/academic/nerd/whatever) but I'm seeing a different strain of that directed towards women these days. Namely, the 'if you're skinny, you're a snob/hater/fat-shamer/etc'.
Fact is, people need /something/ to complain about and, in some cases, to take the blame off of themselves. If it's not race, it's size. If it's not size, it's going to be something else.
People need to stop being so.... /people/.
