Why is everyone so toxic? (I'm starting to mutate from all this radioactive waste)

STOP Before you say something like "you must be new here", just don't. No matter what I do during a game I always end up with people that may genuinely not know what they're doing or just want to grief, afk or feed. But most of all I encounter these salty shits who think they're better than everyone else. Whats even worse is that I'll play multiple matches with them and never see that message saying "a user you recently reported has been banned by the tribunal" or whatever it is. The main source of this salticity is people not getting the rolls that they want. Which is partially because of the new 'champion select' that never ensure you the exact role you want to play especially if you're only queue-ing with one other person, but this isn't a thread begging them to bring it back (though it would be nice). I think that Riot should start cracking down on people reported for unsportsman-like conduct because I for one am getting tired of playing with 12 year olds that just want to verbally shit on someone.

We need an end to this.

Thoughts?
