There are different types of skinny, I agree with you. However, I would class get as slim and toned - of course she is not fat in any way, and she might have a good body to do VS, that's correct.
However, most girls on this site prefer the very skinny look and think that VS angels are too big for their liking. That's not an attack against you, that is just stating their preference.
People are getting in your face because you started talking about anorexia - please understand that many girls in this forum react very badly to that because many of us have to face constant "omg you are so skinny you must be anorexic go eat a cheeseburger" from people around us.
