Dear Rauf, Either you dont realize or you are trying to dilute the danger of Islamic ultras. When some caste is killing another caste, they are not at all thinking of 'HIGH CASTE RULE' OR to form a 'DAR UL BRAHMIN'. These are local restricted conflicts. But when an Islamic ultra is acting - he is motivated by concept of ISLAMIC RULE ALL OVER THE WORLD or DARUL ISLAM. He wants to cleanse all other communities or subdue them to fly the flag of Islam over them. THE MOST DANGEROUS IDEAOLOGY IS THAT MUSLIMS OF WHOLE WORLD ARE ONE. This ideology is sure formula of never ending killings in the world. Imagine, one fine day, a dark child from a family of fair skinned people declares - ALL BLACK SKINNED ARE MY BROTHERS, SO I SHALL ELIMINATE OR SUBDUE MY FAIR SKINNED PEOPLE. This is what the spirit of GLOBAL ISLAM is DOING - denying the need of loyality to a country or state of birth or citizenship. For example ; will you accept a nepali worker earning bread in your city but abusing your own city or? I am just giving very mild examples. Just think over and you will realize the difference between ISLAMIC terrorism and the inter-caste killings. Of course both are bad.
