Just a question. Will I get banned for Mute-ing All in every match?

If I mute everyone in every game because, I may (or may not) have been a toxic player who couldn't just stop typing when I got into an argument, would that be a reportable offence?

Not communicating with my team isn't something that I want, but I believe that it may cause me to be less toxic in games. I'm just not a very mature person and sometimes I say things I never would "in real life", that doesn't make it alright to say it in league of legends, but there is the gap when looking into a computer screen that's bridged when it's my real name and my reputation on the line. I just don't want to be permanently banned. I'm trying to change my train of thought to just mute a person when they decide to be rude but, I find it hard sometimes. When, even if you are really nice in chat, the person still decides to bring race, sexual orientation, or my intelligence into the conversation. I'm feel like I'm totally misguided in thinking that I should mute everyone, but I don't have a suitable alternative that works for me. In the end, I just want to know if I will get banned for permanently mute-ing everyone in every game, I know it's not right, but I believe it's what I need to do now for myself until I become more mature.
