I don't entirely agree; sometimes just forming a particular opinion or making a particular judgment has to imply some further, unstated conclusion/inference or why make the observation out loud?

To me, "She's overweight" is only needed when a doctor/nutritionist/dietitian/cook is asked why another person is on a diet? "He's good-looking" implies one likes the person's looks, "She dresses well" that the person stating that likes the other person's style. That no added on conclusions are added, that I don't state that I'm going to jump the good-looking guy's bones (or am telling you because I think you might like to) doesn't mean I'm not being judgmental.

I may be being judgmental about this particular word but I think judgmental is usually perceived as a negative judgment. If I say, "She's overweight and that's good; all women should be slightly overweight", people might agree or disagree with my judgment but I don't think they would find me judgmental?
