When people feed and then use damage graphs as a way of saying "you're bad"

I've seen this a lot recently. People pick bad fights and lose and feed, then they complain that you are "useless" because you are clearing the wave at turret, or doing something else actually constructive. At the end they link damage and say "YoU Do LeSS DaMaGe tHaN Me". Are people really that special? Of course I do less damage. You try to fight every chance so you will do more damage, but that's also why you die 40 times.
