There is no template towards negative feedback, the fact it is feedback is in itself useful. It is when they offer no feedback and just complain with no content or salient points.<p>But using the reductio ad absurdum defence, whilst can be fun is not productive and akin to cutting of the corners of a square block so it will fit thru the round hole. With that there will always be a difference of opinion in many areas of life, but pursuing a path of time utilisation with somebody who is not going to add anything to the matter at hand is never a good use of time. More so when you learn more from just walking away, their loss.
