the life of a silver player

I'm on a 7 game lose streak in loading screen right now. before you read these first couple of sentences and say "oh my god another trash silver player complaining about afks and trolls" just read the whole thing first before giving your thoughts. Last game i had a 1/10 udyr intentionally feeding [and then at the end of the game afkd] because he thought we were going to lose 10 minutes in and we didnt say yes to the surrender vote at 20 minutes. i got to their inhibitor but we ended up losing because of him. i was in my promotionals. now you could be saying "oh its just one game, i doubt that its all your games." i have proof that my last 4 games i had the udyr, a duo top lane amumu jungle troll on my team with me, a singed mid and finally a duo 0/10 bot lane. The duo 0/10 bot lane are not trolls. they are not afkers. they just fed. now everyone has games like these right? i ended up looking them up and in every single game they have played it was the same thing 0/10 4/9 4/18. crazy stats that i can't just brush off and say wow those guys are bad. what i said to myself was why haven't they played normals to perfect their laning? to perfect whatever they need to. their teamfight their mechanics they map awareness! for i have done the same myself! i'm no god so to speak for if i was i would have carried my games. but these loss games are not FULLY my fault. sure, i could have carried if i was good enough. and maybe one day i will. but the point of this post is why are these players playing RANKED and ruining others games because they are not good enough or should NOT be good enough to play ranked. i have had my share of games where i have gotton angry and called someone out on their feeding or asked them why they are playing ranked. but i am no obnoxiously toxic person. i try not to type in chat to argue with these feeders/afkers/stubborn people but they're just so ignorant. if only they could see what they are doing. this one game we had a talon mid and he was getting camped. instead of buying wards he had blamed our lee sin jungle for not ganking the 7/0 lissandra with ludens echo level 10 while lee was still level 6 and so was talon. i tried telling him to switch lanes with me and i would handle lissandra but his ego was too high and he decided he could handle a 1v1. for the next 8 minutes he went 1/12 and proceeded to blame our team. And i dont understand when players think just because they have a better KDA that every choice they make is the right one. If i try to tell them otherwise they just say "stfu noob ur [enter kda here]". its almost as if theres nothing i can do. am i just going to be here forever?
