Is this what physically fit people mean when they tell overweight people to get in shape?

Every time I’m on some forum, in public, or just hear the topic come up it pisses me off. When someone that is overweight or out of shape asks for dating advice the first thing someone tells them is to lose weight. When someone sees an overweight person in a relationship with someone that is skinny or physically fit people ask how the overweight person got with the skinny person. It seems like skinny or physically fit people act like overweight people have to lose weight or be in good shape to deserve love or be worthy of a relationship.
