“Yep.” = I agree with you and support your position. No further explanation required.
“Nope.” = I don’t agree, but won’t elaborate, because I might have to engage in logical discourse that requires more thought and effort than I’m willing to provide, and I might not come away feeling like I’ve “won”. However, I still want the attention that posting provides.
I wouldn’t come at you this hard if you hadn’t gone after chyron for similar behavior.
Speaking for myself, to an extent my faith teaches me that there is an element of understanding about faith that can not be explained through rational means, and therefore attempting to do so is somewhat futile by our own power. So if I don’t elaborate about it, one reason might be that I’m not sure it would actually improve understanding instead of merely prolonging the argument.
