"Omg, I carried the game for u guys and you still can't do anything! No wonder ur Bronze!"

People who say the following lines. If you're gonna say what's in the title and then do what's above this line, then what difference are you to them?
Just yesterday in ranked, My afk support bitched at me when they came back, saying I suck for having too many deaths, Ahri ADC is stupid, etc. Then I carried the game and had the only positive K/D on my team when I destroyed the enemy nexus.
