I believe the answer is yes - some people naturally command more respect or attraction, regardless of what they do or say. Humans are mostly pretty judgmental. When we meet people we make all sorts of inner assumptions and associations based on how they dress, their facial features, their height, and how they hold themselves. Someone with a baby face isn't taken as seriously as someone with an older looking face. People who slouch or have shifty eyes don't command as much respect as people who stand up straight and speak with a firm voice.
Sexual attraction is another matter entirely. Although the things people do and say can make up for a certain lack of looks, I have definitely found myself much more attracted to people I knew nothing about than guys I knew to be nice or smart. Attraction is an individual and sometime inexplainable thing though, so I'm not quite sure what kind of comments you're looking for on that topic.
