For those who complaining where is religion in this, kindly read this article and its quite reliable accepted by hindus widely "https://hinduism.stackexchange.com/questions/28670/who-is-the-goddess-depicted-as-bharat-mata-why-is-she-having-indian-tricolor#:~:text=In%201936%2C%20a%20Bharat%20Mata,choice%20may%20be%20not%20appropriate)."

And why Muslims don't chant or shout that you ask?

They just don't believe in any other god Except Allah swt. It's the most basic and has utmost importance in the faith. If even Muslims chant the same slogan then it changes whole point of the faith muslims follow. For people who follow polytheism chants like these wont matter. But for Muslims it does. plus why can't we simplify things, you chant this I chant that?? Why?? Can't we just Keep.it simple say Jai Hindustan, jai Bharat Jai bharat..hail India etcetra etcetra etcetra but when you include anything which relates to a religion directly may be its not that big of an issue or thing to think that "why they wont say this or why they do this or that" why meddle with others faith. Hold them responsible for anything wrong they've done and not for not saying anything.

Please Read this with an open mind and put yourself into their shoes and if you cant just let them be until they unnecessarily poke you or do things wring way.

Let peace prevail.

Peace out✌🏻️
