chat penalty system is unreasonable

Me to RIOT: I would like to complain that your chat penatly system is too severe. It's not fair to the player that they are in constant jeopardy of being penalized for blowing off a little steam especially when another player can use passive aggressive statements or actions, or bait someone into an arguement, or refuse to cooperate and cause a loss, and then in return report me for being negative because I complain in the game. I'm not even swearing. This is the only online game that I've played so far that even has a system like this. You can go live and say whatever you want, but if you type it youre penalized. If RIOT feels back and forth aggressive chat between players is such a point of contention, then why even allow a chat at all? Or why not just ban the chat feature for repeat offenders instead? What's more is that there is a mute feature in chat, but instead of using it, players just bait each other into arguements and then your system penalizes over the ensuing conversation. If there are people that are so sensitive over chat then why don't you just obligate them to mute the "aggressive" player instead of constantly making reports because they get their feelings hurt over nothing? The chat penalty system is broken and unreasonable.
