HHH, I think the conditions now are a lot different than say 15-20 years back in India and also around the world.
Radicals maybe on the rise, but mass opinion can more easily be mobilised these days by office going individuals, students. Earlier only radicals had motivation to take efforts and reach people because of its difficulty. Now all our voices can be heard much more easily, to a very wide audience.
So, I don't think it is necessary to be radicals to stop radicals from other religions. How many of these so called radicals do you really think are following whatever is said in their holy books? Religion has long since been removed from our daily lives. It is only used for (negative) arguments and identity.
Bottomline, I think the world can only get better. In this information world, truth has overwhelming odds to triumph, than deceit. This is what god, supposedly, always wanted.
