See this is the problem why Muslims do not fit in properly with other communities. You think whatever you believe and whatever you think is the only truth ? While I am no Hindu myself , infact I do not belong to any religion I do enjoy Diwali and crackers , as well as love the delicious Eid food at my muslim friends and Enjoy Christtmas celebration . Here in India no one from any community dares to object another's festival or celebration, be it majority or minority . It might be waste of money according to you , while it might not be waste of money according to another people so why should he not celebrate ?
