Aray yaar why are you arguing with them? No matter how you slice or dice for them its a vijay.. be it surrender to Bin Qasim or the last standoff... Just enjoy their BS and have fun... :)
So your Sindhis, Bhuttos, Chaudharys, Rajputs, Gujjars, Ranas , Maliks,Punjabis even your Allama Iqbal and Jinnah were Arabs :) May you should do better trying to hiding your ancestory. :)
Well you see in this propoganda , they didn't teach you that your Sindhi ancestors defeated and killed Arabs expeditions 15 times before falling to Bin Qasim, albeit who was also revenged. What a shame.
