They make sense if you imagine it means you're staring at anything with eyes. I can conjure up in my own mind that squinty means anything.
The difference being that, in central Iowa, "Squinty's" or "Squinny's" reference squirrels, not asian people. (unless you are a racist, which ironically most of the people who took offense to this tweet are)
In a central Iowa context(where we live and go to school if people haven't noticed )nothing was wrong with this, but a bunch of self righteous people used it to champion their cause of anti-racism, when nothing racist was intended.
Then these same people go on to print an article where they characterize ISU students and faculty as flat out racist.
That is the ultimate irony, and it makes me so furious that I really want to punch people who made that article.
I'm not trying to look at this from the perspective of a white, middle-class American from south central Iowa. I'm trying to look at it from the perspective of an Asian student studying abroad, which is the sort of thing you have to be aware of when you're a member of the media. You have to identify with your readers as best you can.
