They are people who feel morally superior. If you put one on the spot, they'd break. Or at least I could and did break one of those people before. I broke them with philosophical blunt logic.
I broke them by using leprosy on the face as an example. They acknowledged that the sight of leprosy is unpleasant to look at. From there I broke through their morals by saying how can you say you love someone if you can't even handle looking at that person's face, the part of them you will look at the most. Throughout your entire relationship with them you will always experience a sense of unease, disgust, when you see them. A sense of dislike towards something about their appearance. How can you say it is what's on the inside that counts when you are constantly bothered by their appearance? You will never be completely happy with them because you are repulsed by their appearance. Thus this relationship will always have tension. Tension caused by the unease you have towards their appearance that you continually deny being a problem. If the blistering on their face was not a problem, you would not feel disgusted by it, their appearance caused by leprosy.
They tried to counter my argument by saying it is just a medical condition. So are psychological and mental disorders. If a person struggles with a disorder that makes them argumentative and defiant, will you hold that against them or can you tolerate living with someone who gets angry over the simplest things and throws objects out of rage? Or is okay to reject someone because of their personality that has been tainted by a mental condition and behavior which beyond their control.
They lie to themselves because they want to feel like a good person. Like they stand for something good when in reality they have never been put in a situation that challenges their belief. If both pieces of meat tasted the same, but one looked more appealing, why settle for the less attractive one. Because you want to stand out?
