Understanding thread

In the Thundercats episode "The "Thundercutter" Paul Newman voices a conviction that I would like to discuss...

"It is my belief, my code! And, just because you do not understand it, that does not mean it is wrong."

Please explain to me the meaning of this.

he belived this code of his or her, it doesn't need be explain. he or she believes that soo simple or easy to understand, everybody will get it!

really base on someone's ego, people think like this. meaning, just common sense - that everybody thinks the same way! reality check - pepole don't think the same way!
