There is no organic or physical link or similarity between the RSS or VHP on the one hand, and the Ku Klux Klan and Al Queda on the other. These analogies are made by people who are a) trying to sound cool or b) who are simply grotesquely ignorant. The KKK and Osama are far, far more ideologically hard-edged than the so called right wing Hindu groups. They are much more willing and inclined to use relentless violence as a means of achieving their goals than the Indian organizations you mention.
