Why Indian, Hindus and Pakistanis are taking a side in Shia-Sunni war.

I don't understand why Hindus are being so stupid. After the Iranian killing of Indian, Hindus are stupidly defending Iran and Shia. Do Shia-Sunni really matter to you? Ironically, Pakistanis are also being more stupid by defending Saudi and Sunni side. Both Hindu and Pakistanis are ready to give their life for Iran and Saudi. <br><br>Why do you care about Islam? It is not your religion. It has been proven that both Shia and Sunni hate any Hindu or polytheist. When Indians and Pakistanis will learn to live in peace and stop hating each other. When will the Hindus come to this realization?
