"You'd be pretty if you didn't have squinty eyes" Okay, but what the actual fu-? What's the point in telling me that?

Jokes on those guys,because I'd still be ugly without the "squinty"/"small"/"ethnic" eyes 😂😂😂
No, but seriously.
At least once a week someone has to point out that my eyes are "weird" though usually people don't go that far with it (except for when I was in middle school/high school I definitely went through a lot of bullying over my damn eye shape/size because kids are mean) but occasionally- most recently this morning- I do get the whole "you'd be prettier if you had normal eyes, your eyes are just too small" or "ethnic eyes don't look pretty on you" comments... I just laughed awkwardly the first few times it happened but now I just say smartass/sarcastic replies back because I'm petty.
I don't understand what people get out of saying that crap though...?
