I honestly dislike this game's community

So I just played 5 or 6 games, and I've had someone either intentionally begin feeding or just goof off and grief their own teammates every time. All because they were dissatisfied with the way their team was doing things or they got butthurt by a comment that was said by another player. I can honestly say that I come across people like this in probably 50% of my ranked solo/duo queue games. Of every online game I've ever played, League of Legends honestly has the most toxic community I've ever come across. It makes me wonder if higher elos aren't as bad. It makes me want to climb up there to find out. But I can't really climb if I'm having afks, dcs, rage quitters, and griefing in every lobby I enter. Sure, I understand it's a competitive game and things get heated from time to time. But this is just ridiculous. To top it all off, they act all innocent in all chat and claim that the entire team is being toxic and that is why they're acting this way. A majority of the time the enemy team actually buys into their sob story or just thanks them for the free win. This is why I hate this community. It has no sense of moral decency, and everyone seems to be a cutthroat piece of garbage that doesn't care about his/her fellow player. I feel like the tribunal does nothing to people like this simply because Riot is making money off of them. Thank you and goodnight.
