I've lived there and experienced exactly what you described from Gulf Arabs & Levantines Arabs- whom are commonly light-skinned.
I faced the most taunts and shoves as a Pakee, but the second most taunted one was the Sudanese in the class. Even a teacher made a racist joke about his color.
It was heartbreaking as he was the only teacher who was willing to stand up for me and using the required force to shut those bigoted Arab teens up.
I've read so many news reports of Arab hate mongering towards Africans & Asians, which is all why I am so bloody resentful of this "Ummah."
Only last night I saw a poll posted by a South Korean showing which countries had negative reception of Pakistan's influence. Turkey was ranked really high in negative.
Not that always trust polls and not that I feel that way towards all Turks, but honestly sometimes I feel as if those Ummah type of Pakistanis are a separate nationality from me. I feel so alienated by them.
It's like I'm dealing with these Middle Eastern scumbags but as Pakistanis in the flesh and bones
