The most annoying kind of toxicity(to me)

(Side note: This is kind of a vent. I already know that I should be muting these people and already do)

This is a vent post about a certain group of toxic players. They're players who are toxic, but act like they know what they're flaming about but really don't. Common examples of this are the "why are you focusing the tanks you x(insert slur here)", "why didn't you follow the enemy talon as kassadin you x", or things of the like(they're of course followed by actual flame, that's just the starting point for these kinds of people). The reason these people are so annoying to me is because the answer should be simple, just explain that you can't follow the enemy talon and that he probably shouldn't invade the enemy jg as master yi when you will never have lane priority, but it never works like that and the only solution to this is muting these players. Issue is- muting them doesn't really help anything. They have what I like to call "hashinshin syndrom" and will continue to afk, type, and not focus on the game, complaining about some perceived mistake their teammates made when in reality it was their own poor play, and sometimes get their teammates to type essay rebuttals to them. Generally this can really impact your team unless you're stomping the enemy team, where it really doesn't matter.

There was really not much of a point to this post, i've just been running into these players almost every single game i've played today, so it's been getting rather frustrating. I'm interested to hear other people's opinions on this.
