Guies like you cannot understand advanced concepts of philosophy as you are brought up like frogs in a well. If only you can understand what is unity in diversity you will not talking like this. But if you go back to the roots , it was only Hinduism (sanatan Dharam) which has been existing before any of your so called modern religions. Hindusim has been existing and will exist , because of the freedom of thought. Because a hindu is not in a well and has the ability to think beyond his religion and culture . Be ashamed that you do not have the ability to see other peoples point of view because the network of your brain is very small to that of an animal.
