Venting here before i explode in game

I just had the most tilting game over the last 30 days, I almost lost my shit. I went fid jungle and my top WW decided he wanted to steal my blue instead of help me get it... Then when blue spawns again the ENEMY ww was in the bush so i lured it up and pinged danger and assist me, he comes and steals it AGAIN then ints it to the enemy WW by chasing him all the way to tier 2 top tower from our blue buff. repeats this 3 or 4 more times all the while my mid (Yasuo.... shocker that hes a fkin twat right?) tries to tell me im in the wrong for telling him to stop stealing my fkin blue buff as JUNGLE FIDDLE when my W eats my whole fuckin mana bar to kill multiple mob camps. he persists to troll me the entire game and int my jungle buffs to the enemy warwick and the yasuo defends him for this, we ultimatly lose because of it... like... i HONESTLY dont understand the stupid ass fkin people on this game, the ones who do this, and the ones who defend it.... Can someone explain to me WHY anyone would defend this type of trolling? they werent duo que'd from what i could tell. the yasuo player was simply stupid. I cant even express how bad i wanted to explode on both of them but I didnt. playing this late at night seems to draw out even more of the shit stains that smudge up this community than normal.
