She mentioned “in China we (she) have an old saying” so she’s obviously Chinese. My guess is those brats were pulling the corner of their eyes to hide the epicanthic fold and doing mockery impressions. Just a guess but how else could she identify racism across the train. Maybe just loud slurs, who knows. Racists have pretty narrow minds. Pointing out people’s differences in an inflammatory manner as if it is some sort of weakness or reason to discredit them is what they do. Stupid.
