Too many men and women are superficial and shallow. Would you want a man (or woman) who only likes your body without getting to know you? Of course physical appearance is what initially attracts us to others, but it is only one facet of a person.
It is my opinion that people who "fat-shame" or similar are merely reflecting their own insecurities onto another. What business is it of theirs what size or shape my body is?
There are plenty of healthy, happy and sexy large women, as well as plenty of unhealthy, unhappy and disgusting skinny women. Don't worry about your looks, just be the best you can be. AND be kind to your self.
