Overall League Community Thoughts

While playing League, have you ever been raged at and called a "12-year old little boy who can't play"? Ok, in my case, sometimes I can't play because of a bad game, but think about it. Why does the majority of the League community insult someone using their age (and then add other questionable words XD)? I am DEFINITELY NOT 12 (I'm not putting my age, but I'm a teenager lol), so that type of comment made me think "What. The. Actual. F*@&." I mean I know people will make up their own way to insult people, but this type of ridiculousness has TO STOP, because in the end, how many 12 year olds are playing this game versus people over like 15?
