I took what FlyDeltaJets87 said as a response to your comment that "a lack of planning on their part does not constitute an emergency on your part". (Especially as that was what was quoted in their response )

Not to put words in peoples' mouths but I think the point was that there are many reasons people ask to switch and many of those reasons have nothing to do with a lack of planning. So for people to get so bent out of shape because someone had the audacity to even ask seems to be a bit of an overreaction.
