This issue has come up in the past on other forums, I think one of the answers that I identified the most with was saying: "I'm not sure I agree with that, and I have a few significant concerns. I'm not comfortable agreeing at this time. We'll have to take this offline and come up with a well-formed (answer, options analysis, options assessment)." You can also try to push back and ask for an option analysis or position assessment: "I'm not sure that the details are clear on this. Can you provide a (proper) option analysis on this position?" In this case bureaucracy is your friend.
