You said everybody is shallow because everybody is into conventionally attractive people. That's literally what you said in your post. And it's utter bullshit. So i gave you a very short and by no means exhaustive list of examples why people would not be attracted to conventionally attractive people. I and other people could go on for hours who else would disagree with you. "Conventionally attractive" is an inherently cisnormative, heteronormative aesthetic, most people i hang out with do not resonate with it at all. That's not even getting into the rampant fatphobia and the white supremacist thinking that's also baked into the accepted concept of "conventionally attractive". And many of the acespec people i know just do not judge attraction primarily by physical features and do not get how you can already tell a person is hot just by looking at them. Your entire assumption of what "everybody" finds attractive just very quickly stops to work outside of your little straight people world. ofc i'm gonna call that out. That's not even beginning to unpack your implicit assumptions about valueing physical attractiveness higher than other traits when determining how attractive a person is.

The term conventionally attractive already means that it's an artificial societal standard that's forced on people against their will, against their natural desires, and frequently against their needs. That's what "convention" means in a societal context: an enforced and policed norm.
