A couple of points.
This is Philadelphia.
It’s a sh$thole.
Secondly, American blacks can be extremely racist against East and South Asians.
I’ve been at the receiving end on the basketball court in college. And I absolutely loved beating them and see the rage when they expected us (desis) to lose.
I’ve also seen young black folk abuse East Asian women verbally fairly commonly like for example mocking their accents etc.
Also, it’s ironic this fool with the hijab is behaving in this manner.
But I’ve also come across really nice and good blacks as well.
So I would chalk this up to lack of education and ghetto mentality more than race.
Also in this particular case jealously.
The girl getting beat down was cute and had nice hair.
The attackers were likely jealous.
