Basically, I believe that for a lot of people and probably because of some negative experiences a person had, he or she can make any superficial thing a very important requirement for dating someone. If this is the case and no matter what the reason is, then I don't think the person is really that great to date to begin with and has some room to grow as a person. When something isn't going in that person's favor and has a need to vent about it, then I think the person is really the problem with a mental condition.
I think it makes sense to ignore physical attraction and see it as a natural thing while being mindful about some things that are superficial. People were born to look a certain way and they won't be able to change it in a natural sense if it's not in anyone's preference. I think it's going out of harm's way to spend additional money to do plastic surgery to look like someone else and compensate for lack of self-esteem in one's appearance.
It's much more stronger and meaningful to grow as a person while excusing things that you can't change about yourself as superficial and recognizing the things that you can naturally change while desiring to do so. It doesn't hurt to make yourself look nice on the exterior like working out, styling your hair, and wearing better clothes.
