"You don't have the right to give your thoughts to the team because I have a better KDA and Rank."

I don't know if I'm the victim or if whoever arrogant enough to think that the title statement is true is the victim, but lately, in my blind/draft pick days instead of playing in ranked to climb out of my elo-hell, my matchmaking teams were a little bit... 'tipsy.' I don't like to criticize or "flame" people, but I slightly give them hint(s) whether or not they're doing good or bad in lane. Sometimes people respect and accept my opinion or 'mild criticism,' while other people claim that I'm salty, I'm flaming, or whatever criticism-berating adjectives you can think of. I spent the whole night laughing and at the same time have a need to feel the reason WHY there is a great majority of players like the one I'm going to explain about: Now I'm no feeder nor a good player, so I would call myself an average league player. But after a huge, tragic loss streak in both blind and draft pick, I decided to pop in an ARAM game to cheer myself up a little after decades of disappointing losses. The first ARAM game was good, resulting into a win; making me feel satisfied. I popped into another game of ARAM but this one was UNLIKE the other ranked games I've ever played. I first want to clarify that the second game didn't go well for me and my teammates. A Garen that thought he could 1v5 to a Karma who claimed to be in Platinum but played like a bronze. The target "antagonist" in this story is the Karma, with the others silently watching the whole scene unfold. After losing an inhibitor and having an Ashe suddenly commit suicide with the 1v5-wannabe Garen and the Platinum-Division Karma, I just did what normally other League players do: react to the situation. I didn't flame, heck no. I just said that try not to 3v5 especially if the whole team isn't around to help, and also not to overextend in lane because they had a Malphite with an Ult cooldown of a Yasuo's Q. The Karma didn't seem to tolerate my barely-exaggerated complaint and as I quote, told me this: "I have a better KDA so stfu plz thx." Now that really made me laugh in a scoffing manner, not to mention even though the Karma had a better KDA ratio than me I at least used my skill shots in an effective way; for I was playing Morgana. Ater being flabbergasted, I typed back that it was my criticism, and nevertheless, I said it in a flaming or berating manner; and KDA didn't matter if I'm stating my opinion. I also told him that we were almost in the same line of ratios. He then started to say that was HIS 'opinion' and told me that I was a 'scrub' to him and I should, what a boosted player would say, to shut up in a condescending matter. He then started to brag about his rank, saying mine is no better than his; leading to the end of the game. I know this is an average toxic argument, but I don't like it when your opinion or criticism, that's probably going to help the teammates a mild bit, will suddenly have its case closed because your KDA doesn't say that you are 'worthy' enough to make a statement or opinion. What if there is somebody that has a higher intelligence than I am at this game? That'll be fine. But he or she won't say something arrogant like "I'm better than you because of your ranked." or anything above those lines. To be honest, I think that the "I'm better than you at this game because of my possibly-lucky-KDA-or-rank so your thoughts and opinion don't matter" thing is stupid, and I like to write about stupid things like this.
