Unlike islam, hinduism is not in denial.
The age of marriage for hindus have consistently risen based on social, political and cultural relevance.
Manusmriti is for the Satya yuga which is more than 15,000 years old. Mahabharata was for an age more than 5000 years old.
Gautama smriti is for an age more than 6000 years old.
Hindu smiriti change with time, unlike the child marriages in islam.
Just a few centuries back 33-year-old King John of England married 12-year-old Isabella of Angoulême.
But unlike the islamic and christian "laws", a hindu is not allowed to consume the marriage by law.
BTW the age of Aisha was six and the marriage was consummated when she was 9.
Will someone please ban this maderchod before we start posting how hindu gods have been raping each other?
