I'm getting pissed off with smurfs who think everyone else is as good as them

So, I just played a game with this asshole Shaco who flamed me and the rest of my team, had an extremely negative attitude, and kept going in all chat saying to report me for intentional feeding and just wouldn't shut up for the entire game from like 10 minutes in, all because I died once when I got ganked by their jungler. By the end of the game, I did end up 0/9 as Cho'gath because I just gave up on that match since Shaco had gotten our entire team to start arguing with each other, so nobody was putting any effort into trying to win or anything, so I thought fuck it, why should I?

About 15 minutes in, I pinged for help, so he came top and tried to gank, and I had no idea what the hell he was doing. He didn't tell me what he was gonna do, and so no matter what I did, he'd bitch at me. I quit pushing and let Teemo get closer to the turret, I got bitched at. If I pushed harder, I got bitched at. He apparently sent in his clone for some reason but stayed behind, and I had no idea what he wanted me to do

After that gank, he said I was hopeless and just refused to try and gank anymore and just kept pushing our teammates to surrender on 20. Also before he ganked top, he was whining about bot lane not doing this and that and blah blah blah. And just a note, I'm in SILVER IV. Not Diamond, not Platinum, not even Gold and yet he expects everyone to be on his level, whatever rank he is on his other account(s). Not everyone, especially in Silver is gonna be as good as him. Oh, and the best part about it was in champion select he said something like "I never go into a game expecting to win because I like to always have fun" The irony is he made the game unfun for everyone else by being a total dick, and what he said ingame was definitely not something a person who was "having fun" would say

So now that I'm done explaining what happened to lead me to this post, my message to all you smurfs out there is basically: Not everyone is as good as you, especially if you're on a smurf account. Quit bitching at people and flaming them because they aren't doing as well as you are, because that's most likely the reason they're ranked what they are. If you have a problem with people doing poorly in a different ELO, stay in your own ELO and quit looking for an easy win and a way to feel good about yourself by putting others down just because they aren't at the same skill level

Thanks
