I do see that their support for suicide bombings is coming down, however there attitudes towards religion in general will not change. Imagine the rest who are just extreme, not the extreme of the extreme who support suicide bombings.

Lastly, Modi being elected is not because of him being any extremist. He was elected because he was a brilliant administrator at a time of economic slowdown and governance apathy in India.
