I don't think the generally toxic attitude is involved in this, mostly because of the post about trash talking made by Riot. Also I've had plenty of friends that said much worse things and got away with it.
Just in case you want to know the context of that """"""insult"""""", a guy was bragging because he was a yasuo main. Literally a scene that you see in most bronze games, I don't see anything wrong with this.
