Why can't I argue against claims of suffering? - lemm.ee

I don’t know that I understand the question. Whose claims of suffering are we talking about?

Ok here’s an example.

Bob : “When I put on a dress people look at me funny, which is hurtful.”

Rob : “Meh, you don’t look very hurt to me.”

BAM. Rob has argued against Bob’s suffering, which is a sin. And now everybody will justifiably hate on you. Granted.

But why, exactly? What’s the logic here? Why does suffering get excepted from analysis?

Rob's is assuming he 1) sees everything, 2).didn't or can't miss anything important, and 3) that his interpretation is correct.

That's why it's arrogant and stupid and people get annoyed.

Seriously, have you never been upset or hurt and had someone try to tell you that you're not?

Rob is simply using his powers of observation. Surely you are familiar.
What in the world is Rob actually tangibly observing? The inside of Bob’s brain? Is Bob wearing a sign that says “my current emotion: happy & content”? The point stands that Rob does not see everything and isn’t necessarily correct about what he thinks he sees.
You just can’t trust Rob, can you? Is this the fate of anybody who contradicts your hypothetical principals?
