I will be in the minority, as usual. I am blessed with good looks. But I always thought that I was not - thanks to my mother. I never fully recovered from believing that I was not good-looking.
We do create human beings, but unfortunately or maybe fortunately, we are not in control of the manufacturing process. Otherwise with all our good intentions, we may create sinking Titanics. "When things go wrong..."
We don't choose sex, looks, genetic code of our children. We do have some control (we can smoke or not smoke, drink or not drink, eat healthy, et cetera), but "making human beings" is still a lottery. You hope for your child to be at least healthy and you hope for him/her to look good. Not to be beautiful, but to look good (not to be repulsive). For a reason.
If you did not know and it is a fact, human babies and babies look cute so parents will experience love and care for them.
"Ugly" is not just a word. "Ugly" is antonym of "Beautiful". We need WORDS to describe things. Our response to visual stimuli is different - we like to look at beautiful things and we don't like to look at ugly things.
Being ugly is not a person's fault (it depends on what ugly means in each case), but don't fool yourself - you may never say the word, but you are drawn to beauty. I studied sociology and there were studies about the different reactions. Parents differentiate between better looking and not-so-good looking children. Parents always have favourites regardless of what they say. I don't understand why people love to deny the obvious.
I know one young girl - I don't know her, I never talked to her, I see her often enough and maybe she is a good person, but, boy, I cannot look at her. I simply cannot. What gives me the right? My own brain tells me there is a difference between pleasing sights and disturbing ones.
