IIT/IIMs are dominated by higher caste with their so called "intellegence" then why dont they bring it for their own country,havent seen any bringing "tech advances" back home as u quoted .And till today not a single brahmin has come forward to say that he respects a shudra whole heartedly and will willingly marry his sister/daughter to a shudra.By publishing ur view u proved urself a big hypocrite.Coming on to Islam, only a samll sect followers of wahabi are creating nonsense and waging gurellia war which is opposed by staunch muslim countries from where it actually originated like saudi Arabia.U r very ill informed and lost ur way.
