STOP Your propaganda ........you are aware of reality ...............................stop lying & dont be apologetic .
for your Kind information there is no caste system in Buddhism still Buddhist majority areas like indoneshia , malayshia , afaganistaan ,kashmir (parts of Bihar & Up)etc are converted to muzzies .
if people hated caste system they they could have accepted Budhism or jainism .
Iran was not a muslim country they were following zohrashtrianism (in which there is no caste system ) and parsi community in India (like tata ) are war refugees .
now Iran is a hellhole ...................................
check the history of middle east , there was no caste system in that area ....still they were forcefully converted .
if there is not caste system in Islam then what is shia , sunni , ahmadiya , barelavi etc ??
check the surnames of converted pakis most of them have surnames of upper caste Hindus .........or better read Babarnama , akbarnama ,humaun nama etc how they forcefully converted by rapes & murders and yes they are not ashamed of their Crimes .........they are very proud of it .
they were / are just following Mu-HUM-MAD .
This is why muzzies are Unhappy in almost each and every country ,
