Is it just my elo or does everyone in every rank blame others that aren't responsible?

Ok people, I know not all of you do this, but to those who do.. you're freaking losers. I would be 12/3/30 and a mid lane talon would be like 2/15/6 and straight point me out for why we lost. Like come on people, everyone has bad games and when it's your fault own up to it and stop being a typical bronze scrub and actually find where you went wrong and work on it. You wont get out of bronze scapegoating people. I know how every league player thinks their one of the best but you're not and neither am I. I just started playing ranked hopefully as I progress in elo I start getting matched with less childish players..
