I don't personally follow the belief that my religion is right and someone else's wrong and ergo they are going to hell/eternal damnation.. for me that's not what my religion is about...
I may be wrong but I don't think that many people do believe that....
The Quran states quite clearly that people of the book can get into heaven so its certainly not the Islamic position...
It makes no sense to me that a merciful God would send people to hell for being the wrong religion.....
