the former preaches to kill the latter. pls read mr. arvind ghosh's book "the koran and kafir". to understand why this young hindu man was killed. also, pls read anwar shaikh's book "islam, the arabian imperialsim" to understand how the muslims of indian subcontinent got pushed into islam which, if they were allowed access to facts and think freely and had a choice, they would repudiate. there is no reason for the subcontinent muslims to remain ignorant in the 21st century, the century of information made possible, largely and ironically, by the hindus.
