The mute button is meant to be a band-aid solution at most and does not give flamers and verbal abusers a "get out of jail free" card for their behavior. If you can't interact with others in a mature and respectful manner even after being given multiple chances to do so then why should you be allowed to continue playing the game? As far as giving advice is concern even if you're polite and respectful about it if it's clear that they won't listen then you should just drop it and move on rather than use that as an excuse to flame them. If they wouldn't listen to you before-hand then you flaming them gives them even less of a reason to listen to you and what you have to say.
I also find this statement by you contradictory:

And I can control my temper I choice not to because some kids deserve it.
You're getting onto people about using the mute button yet you're the one choosing to rage and flame like a little kid simply because people aren't doing what you want them to do. If you want people to listen to you then don't devolve into a toxic jerk whenever things don't go your way and control your temper like you claim that you're able to do. Besides, just like in most real life establishments Riot doesn't care who started it as they'll gladly punish all involved in the fight-this isn't Kindergarten or Preschool after all.
Basically just grow up and stop looking for an excuse to be a toxic jerk to people and expecting that people will just magically conform to your behavior alone.
