I think you should check your Math skills. They were only 2.5 crore not 7 crore during 1947 (8% of 33Crore) Hindus were around 28-29crore. See the the percentage not the absolute number. If don't know the statistics go and check offical figures (Govt of India). This is not my numbers.
Again, if India going to be superpower not becuse of Muslims breading more. becuse of "More" educated people not becuse of croes of useles muslims.
Why poverty in muslims? just think about a min - because they are producing more children than can support, isn't it? Can you give good education for 12 kids or 2kids?
