Riot encourages trolling.
It seems like this liberal world has taken over video-games too. Now everything and anything is offensive. You can't kindly ask your mid laner to "please stop fighting the yasuo" because it opens up doors to hell from your teammates.
Now now, you better not suggest anything to anybody else, because then you'll be the "toxic one" in the team and give reasons for "everyone" to just turn on you, or specifically those you've given suggestions to.
Of course people would assume it's the way I suggested that they perceived offense, but it's not that at all. It's 100% pride, embarrassment, and frustration from their performance as a player that has them tilted, and immediately on the defense. And while I specifically point out what they can do to immediately improve, examples: (don't walk into the enemy jg if you don't know where he is/without wards), or (please don't fight yasuo again) and their response is "but I'm ryze." or "Shut up" riot has taught us that there's nothing you can do, so accept the free lose. Free lose because the system is broken and if you have 1 troll on your team, chances are that you will have another, and riot expects you to carry them to victory, because your opponents are noobs too. But as the meta switches more over to teamwork and noobs rush into mid lane to fight asap without any resources of conscious decision making... it's a free lose.
So yes, riot forces you to suck the trolls off, and just take it from the back in silence.
Dynamic queue is to thank for this, because odds are, those two trolls are duo and that's why you got paired with them in this COMPLETELY UNBALANCED SYSTEM.
