What whould make me change my belief ?

when am i wrong ? and am i able to consider i am wrong on this topic.

If it is fundamental to who you are and see no possible way to change your mind there is no discussion just arguement.

Same the other way around if it is someone is 100% sure their truth is the truth there is only arguement to be found.

"The sky is green" is only worth a debate if the person saying that is open to the idea of being colorblind
