Personally i am not a big supporter of RSS and its ideology but lets not forget the contributions of RSS when some calamity occurs. They may be termed as extremists but still wen it comes to nation or humanity u can find them raising their hands.
and sorry friend but you seem to be biased against them. There are some other groups who r dangerous to country, some of them are Hindu-extremist and some r Islamic but RSS is doing some gud work and don't ignore that.
