League of legends is it community based???

So i was playing this game and i lost lane and then the enemies kept being very salty but then i just asked why they were so mean when the base of the game was friendliness and helping the community.then they said that the people who say league is community base are just r%%%%%s. So riot I have one question Is league really a community? Or just a bunch of people always wanting to win even if it means just insulting every defaults of your team. IF this is how you really imagined the game a random bunch of people just wanting victory more then playing the actual game. I just need this one answer. I am just really that people just be mean because you dont carry them or they just owning an ennemie. Am I the only one thinking that ----Terranie
