Yeah there are people who judge based on the external appearances. Since it is not possible to feel, touch and comprehend fully one's emotions of joy and sorrow, so people tend to form their opinion on the external appearance.
Being judgemental is not always right, in particular for healthy relationships. The best way is to cultivate an obstinate form of love and try to be as optimistic as possible. When things don't work, judgemental attitude could be a best solution provider, think and move, either closer or farther.
