If you compare ShivSena or Bajrang Dal with SIMI then both of them have various similarities but there is one basic difference that is SIMI is anti-Indian by supporting attitude of isolation. No religion can lead the world. We all religion make this world. Be together by sharing love and trust with each other. This is what our India... Beautiful... Rang Biranga.. let it be like that only plz... don't hurt others feelings by supporting extremism of either religion of any type.
