mohajirs are afraid?

the inflow of mohajirs-burmi-bengali into karachi made mohajirs in majority than sindhis;now-a-days mohajirs affraid being in minority ;due to inflow of pathan/afghani into karachi daily thosands come to karachi by trains by roads;and tempo of arrival of these two comunities is too much fast in comprassion to mohajir-burmi-bengali-bihari migrated to karachi;it seems within a year patha-afghan will not only crooss the mohajir majority but also will challenge mohajirs in varous sphere of life;all clashes between mohajir and pathan is result of these circumstances;;;;;;;;;future will tell will mohajir survive or not?---mumtaz04-05-2009
