A. [0] Familiarity breeds attractiveness.
This isn't a new concept. You can find many advocate groups who want "diversity" in workplaces and higher positions to stop systematic or perceived racism due to non familiarity. How is that different from above? Do you have a choice to be ugly or not? Do you have a choice on whether your body is deformed or disabled? Do you have a choice on being poor?
To little extent, maybe but most can't be helped beyond a certain level.
B. Scale
Night club doing it doesn't affect society as much as a platform with 1.5+ billion users. Of those who are going to vote new policies and may get to a high position of authority later,
do you really want your judge who uses tiktok to sentence you for longer?
You can already find people living in echo chambers online and as more of it is moved online, will you be okay if your child is excluded from something more than a billion people use because she is a bit shorter than normal?
How many of you have LinkedIn, twitter or social media crap that you despise but have to use due to others using them? What will happen then?
C. Awareness
Do you think users are aware that they are being censored constantly compared to real life where you can't avoid meeting different people? If you go to a bar, you will see different people in your way - few "ugly" and others pretty.
<sarcasm>
I propose we stop ugly people from having kids so everyone remains pretty and similarly symmetrical. Who wouldn't wanna live in a world with everyone pretty and same? It's not like we will seek more exoticism after that happens. The problem will remain solved forever.
