tan, My religion tells me to respect others beliefs because there is no one book or god or philosophy. We have motley of philosophies. So as a tamilan, even when I visit sai baba temple, even if I do not believe, I respect others sentiments.
But your book ask you to convert others to your belief. It says that only islam is correct and other's beliefs are incorrect. Same is the case with christianity. Why this case of superioriy complex?
You know one thing, killing in the name of religion started with the advent of abrahmic religions christianity and islam. They killed among themselves and killed others also.
Anyway, Karunanidhi is a novelist and he knows lieterature, one swamiji has agreed to debate with him. Karunanidhi can accept it if he wants.
The point is give respect and take respect. Do not tell, I am the only one correct, all others are stupid and shud follow me.
