Provided the followers of that religion behave properly and be humans first.. all the holy books say good things only thats why they are said to be holy books.. whats written there is not important, whats implemented is important..
And who said there are many women for men.. I dont how its in Muslims but over all the birth rate of girl child is going down and many girls die after birth due to lack of proper care..
Anyway better to have same laws, same civil code for the poeple living in one country.. reservations shud be for all the castes religions based on financial situation..
