What does it even mean to "believe the answer is yes", but "in a way that somehow means" the direct contradiction of that is not wrong?
Do "believe", "yes", and "no" have definitions?

This rhetorical device sucks and gets used WAY too often.
"Does Foo have the Bar quality?"
"Yes, but first understand that when everyone else talks about Bar, I am actually talking about Baz, or maybe I'm talking about something else entirely that even I can't nail down. Oh, and also, when I say Yes, it does not mean the opposite of No. So, good luck figuring out whatever I'm trying to say."
