Honestly where do people get off

The game I just had my jungler gave my laner 2 kills before 8 mins then proceeds to say "fucking retard lost lane". Ok? You tried diving an Ahri that has ult clearly that isn't a good idea but nah thats my fault. Then the Ahri goes at says I'm garbage etc etc should uninstall. Are you serious? My jungler gave you 2 free kills and now I'm the bad one for not being able to beat you? Seriously sometimes the people in this game makes my brain cells die a little. Then at the end our Tryndamere died trying to backdoor and then rages at us for being "useless shits that doesn't know how to capitalize on a backdoor". CAPITALIZE WHAT? Both dragon and baron were down and we were just respawning from a fight so we were all at base. And all of their turrets were down....
