Yeah we are grown ups that report each other because someone called the other "jerk" in game or out of it and it gets punished and this is not offending enough for you?
I am not even Chinese and i get offended by this.There are so many ways to describe someone as lazy...and his skin color has nothing to do with it.
What's next? slanted and puffed eyes, funny shaped head , flat nose, weird way of talking making clear reference to a down syndrome ?
I am not saying that the player wanted to actually offend someone, maybe he was merely pulling a weird humor , fact remains this can escalate in the future.
