Passive Aggressive "smurfs" pls go back to your mains, I don't need your opinion every time I die

Today I had a game that featured the classic big dick Singed player, saying things such as "if you had micro mechanics you be better players" and "low elo Zed and Warwick" and right after he flipped the fed af into us and me and MF as we were both half hp got the fuck out of there, this Singed had the fucking balls to be like "lol Zed come on" if I wanted a "high elo opinion" (I doubt he seven above silver he didn't know how to proxy farm) Then I would have donated to that fucking Last Shadow guy or whatever his name and heard his shitty commentary on why I've never been higher then gold 4. This isn't the first time I've had some mediocre-play, passive aggressive self proclaimed god tier smurf, and it won't be the last. Is this really what most smurfs do? Pumping up their ego by going into low elo games and acting like such a smart ass when someone dies or makes a mistake? Rank games for me have gone so far down the tube in the past year.
