I see a difference also, so I don't think we're in disagreement here. The person it's being directed toward (which strikes me as having some wiggle room, in that you can debate a presumption without necessarily directing it toward the person who raised it, though that's a very thin needle to thread), isn't compelled to respond to someone who disagrees with them. They certainly don't owe it to anyone to do so.Now, I can see a difference between questioning an assertion, and asking for a debate, but the end result to the person it's being directed towards is largely the same.
