It is still punching down but “Brown face” is nothing really like black face which has a history in America as portraying African Americans as lesser human beings that are only worthy of ridicule and caricatures it has roots in Jim Crow and slavery.
Any “face” aside from white face will be looked at
Arabs are not a monolith and specifically Palestinians are facing terrible oppression and should most certainly not be made the object of ridicule.
