UNBELIEVABLE toxicity in ranked queues

Riot, you HAVE to start addressing the toxicity/negativity in solo queue. You make one mistake and your entire team flames you for the rest of the game. They tell you to kys(kill yourself), uninstall, call you mentally handicapped (downs is the most common), etc. Your teammates decide to give up and refuse to work together, they just split push and say "You're on your own". If you happen to make any more mistakes (which is likely because you've been getting flamed for the past 15 minutes) they flame harder. Even if you were smart enough to hit that wonderful reprieve known as the mute button, they still find ways to flame you like dropping a thousand missing pings on your head every time you do something they don't agree with or happened to be another (highly probable) mistake. It is so hard to learn and get better at this game when each and every time you screw up you immediately get to go on the rollercoaster ride described above. Say nothing of the health of the game what about just encouraging a healthy and bonded community? EVERYONE has bad games, but it seems that if you're in solo queue you'd better be an absolute god or so help you... I'm begging you Riot fix this, I know you're losing potential players because of this. I wouldn't be surprised if some people that don't realize there's a mute button have harmed themselves over some of the heinous stuff that gets said in the chat. Sure there's banter among teammates and trash talking in allchat but good lord this is just getting out of hand. I'm an avid league player but I'm getting to the point where I don't know if i want to play anymore.
