The world always runs on only two wheels like a bicycle, one is good thing and other is bad thing. Both wheels will run always. If you are great, then you still can run with only one wheel. But, it needs great efforts and hence no one wants to do the same. Other than these two wheels-( i.e. two differences), we should not see cast/religious/male-female, etc. differences. I am the one, not Muslim, but have helped a great Muslim friend in that Mumbai riot! I only make difference in good and bad. Other differences are not required.
