I've never seen any academic claim that asking a question is the same as making a statement.
I reject your hypothesis that I made any blanket claim about the banking industry being corrupt.
All I did was ask if others are tired of it being corrupt.
That question does not necessarily preclude the assumption that I think the institution is corrupt, but rather anyone who answers the question in the affirmative, i.e. "Yes. I am tired of the corrupt banking institutions."
I never stated such a claim.
