How Do I Stop Being Toxic?

I try not to be toxic ,but when I'm match up with morons who refuse to work together ,constantly do shit like face checking bushes without warding first ,and start arguing because they think that League of Legends a free for all in COD ,then can you blame me for being just a little bit toxic towards my teammates. I think it's keeping me from winning games.
