Do looks really matter in a relationship,would u date a plus size,disabled,or rotten teeth person?

Me and my best friend was having a conversation on people and how shallow and jugemental people are? Her for instance have a problem with to stud female or butches going together(because it don't look right) i told her we still all females so whats the big damn deal.Then we have a friend that was in a 5 months relationship with someone she met online she said she was in love but when she met face to face did not like what she saw and been avoiding them ever since. I told her that is totally wrong and she should be ashame of herself.
