your post is full of misconceptions. Haj is a prayer not a place where muslims prohibit others. How many non muslim want to perform this prayer, Haj.
Who told you non arabs can not be buried in arab. many of those who die there are brought back to India becoz they and their relatives have wished them to buru in their 'watan' i.e nation. Islamic practices do not want to demean you, if you take it otherwise its your misconception.
Lots of propaganda is going on there against muslims, try to know truth instead of becoming part of propaganda machinery.
