Conversion is indeed an act of aggression against Hindus.
The problem is that these days Hindus convert without being forced to do so. They think that changing religion is like changing your shirt.
As usual, it is our self-appointed leaders who are responsible for this situation as they have chanted the mantra "All Religions Are The Same" since the days of the British Occupation and before.
In contrast, Muslim leaders tell their followers that conversion to other religions is punishable with Hell in the afterlife and with death in this life.
The situation will never change until our leaders do the same and punish all Hindus who become traitors and who give up Sanatana Dharma which is the True Religion.
After all, if treason to your country is a criminal offence punishable by law, then so must be treason to the True Religion.
This is why we need Hindu laws to put an end to the conversion of Hindus. There is no other way.
Meanwhile, unofficial Hindu Courts must be established to deal with the criminals as well as Hindu Schools to teach people what they can and what they can not do.
