PSA: If you legitimately want to improve as a player
Then don't let players who are better convince you that other players who are better than you are trash or etc.
I've been bronze for quite a while and I was making a lot of progress and getting so much better off of just watching platinum players playing my main champion, Teemo. I was watching those plat players mostly because they were the only ones on YouTube who regularly did full ranked gameplays on Teemo. Then I joined a coaching group who told me to stop watching those platinum players because plat is trash and etc and to only watch the very limited selection of diamond or higher Teemo players on YouTube and Twitch. I decided that "hey, these coaches are diamond and master's, I should listen to them" and because of this I no longer had new content to watch daily which then reduced the amount of learning I was able to do since I can't play often. As a result I stopped growing as fast as I was as a player and am right back to struggling. I then made things worse on myself by listening to them constantly say how "Teemo is trash, never play that champion" and other such things which further obstructed my learning.
I'm not saying that their advice is without solid foundation, however, in the words of teachers like FoxDrop, Jeremy Gaming Curious, Phy, and a few others: "At the end of the day, League is a game and games are meant to be played for fun", "Your main should be someone you enjoy playing", "Even if your main is a weak champion, if you main it, you can still do well with it."
Unfortunately for me, Teemo is one of the most enjoyable champions all around to play, I like his character model, his voice, his quotes, his skins, and I like the way his kit functions as a whole (I don't particular love the individual abilities by themselves though). While this does put me at a disadvantage, if I stick with it then I can learn to get around that disadvantage. And since I'm bronze, there are things that I can still learn from Gold and Plat players as there are things that they've already tried and tested. I have gone back to watching those platinum players and as a result I am already starting to feel more confident with Teemo again, I just need to rid myself of the bad habits I developed through the ego that those coached instilled in me. By convincing me that those plat players were trash I started assuming that my opponents in bronze were worse than trash for being in Bronze and Silver which made me play more cocky even when I was behind (something that I hadn't done as much in the past" and then when I would inadvertently become a feeder I was excruciatingly hard on myself because "I lost to a trash opponent, if he's worse than trash then what does that make me?"
TLDR:
Don't let others convince you that others who are in a higher elo than you are trash just because they are in a lower elo than the person saying they're trash. No matter who they are, there is always something to learn from those who are better than you and that's the number one thing to acknowledge when you are trying to improve as a player.
