Hi Moshe Rabeinu,
Interesting point. It didn’t really hit me until a few years after I got married. When I was a bochur, I knew my father was wrong but I didn’t understand why. Once married, I started talking to people and realized how people can convince themselves of anything. (Including my father convincing himself that he is the only true mesora, dor achar dor, from Har Sinai.
I won’t bore you with the details. Bottom line is I’ve discovered that everyone thinks their religion is the correct one, and everyone else will burn in Gehenom. This is a universal belief shared by all religions, all chasidus, all cults.
I see two rebbes who are brothers fight with each other; each one’s chasidim will tell you that their rebbe is the biggest tzadik and the other is going to burn – they’re convinced! How do you reconcile the beliefs of the chasidim from each camp? One side (or both) is obviously wrong, yet they are each convinced that their rebbe is the greatest tzadik!
But I’m supposed to believe in Eilu v’eilu divrei elokim chayim when it comes to Bais Shamai and Bais Hillel?!
