i have every religious freedom in india, but still i didnt embraced hinduism. muslims may be wrong but islam is always right.
please check the facts right.Every day your hindu brethern in india is lured by christian missionaries for conversion and in rural places there was mass conversion happening. if possible try to prevent it and then talk about other reconverting to hinduism.
The supremacy of hinduism is nothing but the brahmanical supremacy causing people to move from it embracing Buddhism, christianity and islam etc.
